Compared with digital technology or software, the cultivation and creation of analog technology talents still requires a certain amount of practice and time, but no matter whether the digital technology develops to any stage, it will always be inseparable from analog technology. Due to the large difficulty factor, sometimes even if you put a lot of energy into it, if you lack patience, perseverance and necessary conditions, the investment does not necessarily have a return, but once you have mastered the simulation application technology to a certain extent, then in the future career And will be as competitive as "killer". In order to learn these necessary simulation techniques, the teacher's guidance is indispensable, but in reality, no one can find the most suitable teacher. Fortunately, we can find many excellent works on analog circuits. Of course, we must learn the hardware. There are many good books that can be referenced, but it is still very difficult to easily select a few "Ding Ding" works like needles in the sea. Today, I introduce several books of the Science Press to everyone for reference. Individuals can choose a reference according to their own learning aspirations, ambitions and work needs, but for the enterprise, it is actually "not bad money", the blogger recommends collecting in the library as a reference for new employees. When bloggers used to buy books, they always wanted to buy them when they really used them. They didn’t deliberately collect a complete set of analog circuit application design books published by ADI Semiconductor in Science Press. All of them regretted that at this moment, they really understood that “when they were not used. Hating early, the pain of the skin.
Science Press has introduced a lot of foreign books on electronic circuits. You can buy them through the Internet, but some books can't find any information on the website of Science Press, let alone a detailed description. This is the online purchase of books. The biggest regrets and shortcomings. In the face of the general books, in the end, those books are in line with our current needs? The blogger makes some basic introductions on his own reading and understanding, but it may also be due to the limitations of the blogger's scope of work, so that the evaluation of the book has produced inappropriate results. At the same time, bloggers are not the "all-round champion" in various technical aspects, so this article is for your reference only. The blogger's purpose in writing this article is to hope that it can play a role in inspiring jade, and there are more "technical masters" to recommend some "specific" excellent works for beginners.
The first place to go out is a set of six "Practical Electronic Circuit Design Series", which are respectively "Transistor Circuit Design - Experimental Analysis of Amplified Circuit Technology" (upper and lower volumes) and "OP Amplifier Circuit Design" From the basics of reproducible design to practical applications, "Design and Application of Oscillation Circuits - Experimental Analysis of RC Oscillation Circuits to Digital Frequency Synthesizers", "Digital System Design - Analysis from Digital Technology Fundamentals to ASIC Designs" "ASIC Design of Digital Logic Circuits".
The biggest feature of "Transistor Circuit Design" is that when describing or designing a transistor circuit, the equivalent circuit, load line, and the like are often used. The equivalent circuit and load line are proposed by the predecessors engaged in the design of electronic circuits to facilitate understanding of the working principle of the circuit. However, according to the experience of the author of this book, even if these methods are not used, the working principle of the circuit can be grasped, and there is no inconvenience in the design of the circuit. In the concluding remarks of this book, the author talks about his own learning experience. “Recalling the scene of his own e-learning in the past, most of the books he read at that time used equivalent circuits, load lines, and explanations of theoretical formulas. When I want to design, I don’t understand the nature of electronics. I can’t do any kind of design. I can only follow the mathematical formula and only use the mind to learn, but I don’t really master it.â€
OP amplification technology is the foundation of analog technology and the core of analog technology. OP amplifier is like a black box, which makes people unable to touch the mind, but once you master the technology, it will help the design. For beginners, the author of this book recommends that beginners do the experiments in the book. The author believes that perhaps a more advanced theory will also be due to the wrong connection of a wire, and a numerical calculation error will lead to abandonment. By practicing it yourself, understanding the zero offset and the oscillation changes caused by touching the circuit by hand will greatly help to face more complicated circuits and faults in the future. In the face of complicated OP amplifiers, as a solution to the problem, the focus should be on "understanding the circuit until it can be applied". As long as it is understood, the application is not difficult. Starting from the basic point of mastering the principle, more than 200 circuits in the book can compete with tens of thousands of instances.
If it is only "oscillation", it is a simple problem, but if the oscillation circuit is to satisfy the frequency stability, the waveform purity (harmonic distortion, parasitic oscillation, etc.), temperature characteristics, power supply voltage characteristics, etc., the technical range that needs to be mastered is very wide. In reality, it is still difficult to find an introductory textbook that can be used as an oscillating circuit that is really easy to understand and easy to understand. This book may be what beginners want. It is recommended that beginners can selectively read some of the content that is useful to them as needed. In fact, many of the content bloggers are difficult to use at work. The key depends on the work you are going to do in the future.
There are many reference books on digital circuits. The bloggers will not introduce "Digital System Design - Analysis from Digital Technology Foundation to ASIC Design", but this book has certain value as a reference book for beginners. of.
Since the bloggers have carefully read this series of books, according to the needs of the work, in October 2004, the first five books were included in the company's standing reference books. Based on this, I think this book is very suitable for undergraduates. Graduate students and development engineers have the option to read and recommend it.
The other two masterpieces are "Measurement Electronic Circuit Design - Filters" and "Measurement Electronic Circuit Design - Simulation", which are sisters of each other, and they are all part of the "Illustrated Practical Electronic Technology Series" set of books. A book published by the Science Press in 2006. This is the rare two masterpieces of the author, Yuan Zhenjun, who used the rest day to knock on the keyboard for computer simulation, and took the electric iron for 5 years to complete the experiment. The design and application of phase-locked loop (PLL) circuit "It is another monograph published by Science Press by Yuan Zhenjun. Among them, the “Filter†mainly introduces “from filter design to lock-in amplifier applicationâ€. The theme of this book is to remove harmful noise from the amplified signal and extract the filtering technique of useful signal. Both simple RC filters and complex spectrum analyzers are collectively referred to as filters, which shows that the types and technologies involved are very complex. The circuit that makes up the preamplifier and filter looks simple, but the theory of the filter is very complex, and the focus of this book is on the technology necessary for practical design. In addition to the "Measurement of Electronic Circuit Design - Filters", there is also a monograph called "LC Filter Design and Production". LC filters play an extremely important role in the high frequency field where it is difficult to use operational amplifiers, but When designing high-frequency LC filters, it is often encountered in accordance with such problems, the filters that have been painstakingly designed according to theoretical calculations, and once tested, they found that their characteristics are completely inconsistent. This book is based on test cases, and provides an in-depth explanation of what kind of parameters will affect the impact, and gives the most appropriate practical assembly method. For beginners, the contents of these two books are not used in the design for the time being. After the need or spare time in the future, it is not too late to read them back. Don't eat a fat man.
"Measurement Electronic Circuit Design - Simulation" mainly introduces "from the OP amplifier practice circuit to the processing of weak signals". The most critical part in the process of detecting weak signals is the sensor, but the full effect of the sensor and the detection signal Amplifying to an easy-to-handle signal level requires a preamplifier to accomplish this task. This is the "low noise technology of the preamplifier" introduced in the first chapter of this book. Everything is like this. The most effective way to understand it more deeply is to experiment and make it yourself. If you want to get a low-noise circuit, you must have knowledge of OP amplifier selection, parameter setting, and evaluation techniques. This is the design, fabrication, and evaluation of the "low-noise preamplifier" introduced in Chapter 2 of this book. The role of the amplifier is to amplify the weak signal to a certain level. In general, almost all of the amplified voltage signals. However, for sensors and the like, there are cases where current signals are processed. This is the design of the current input amplifier described in Chapter 3 of this book. In analog circuits, OP amplifiers are indispensable. Circuits using OP amplifiers are almost all based on negative feedback technology. Circuit simulation technology has developed into a trend in circuit design in recent years. This is the fourth book. As an important point of the negative feedback technique, the chapter introduces the "analysis and circuit simulation of the negative feedback circuit". This chapter also introduces the technique of suppressing circuit oscillation. Some noise is easy to eliminate, and some noise is difficult to eliminate. An amplifier that extracts and amplifies a signal component from a noise or common-state voltage is called a differential amplifier. In the high-precision measurement, the differential amplifier technology is indispensable. This is the "differential amplifier technology" introduced in Chapter 5 of this book. application". The signal does not always occur with respect to the ground, but also when the signal component is loaded on a large common-state voltage, or for safety reasons, it is desirable to float the signal off the ground. In this case, an isolation amplifier is required. It is the "Use of Isolation Amplifier" introduced in the sixth chapter of this book. This is a special kind of amplifier, which is widely used in industrial equipment, medical electronic equipment and other fields.
Next, I will introduce a good book, that is, "High-speed digital circuit design and installation skills", which is also part of the "Illustrated Practical Electronic Technology Series" set of books, mainly introducing "accurate circuit board design and noise for accurately transmitting high-speed signals." Solution". With the development of large-scale integrated circuits, the design of PCBs has become more and more difficult, which requires technical attention to the high-speed signal loop and power supply acquisition methods. Whether it is a beginner or an experienced circuit design engineer, as long as you have not designed to tell the signal PCB, then everyone should be a beginner in this respect, then the value of this book can be said to be very large.
Finally, I introduce a monograph on "Practical Power Circuit Design - From Rectifier Circuit to Switching Regulator". One of the characteristics of this book is to pay attention to the basics. In order to help readers design, the author uses a lot of space to introduce the basic knowledge. It even includes some complicated formula derivation, and the author also introduces a lot of techniques in the design process to avoid the readers detour. Ok, then try it out according to what you said in the book!
The "Illustrated Practical Electronic Technology Series" series also includes "141 Cases of Sensor Application Skills", "101 Cases of Analog Technology Application Skills", "100 Cases of OP Amplifier Application Skills", "Digital Circuit Design", "High Frequency Circuit Design and Production" , "Transistor circuit design and production", "high and low frequency circuit design and production", "DC motor practical application skills", "switching regulator circuit design and production" and other important monographs, you can choose according to the needs of the work Reading and learning.
It can be said that analog circuit technology has a wide range of applications, and its depth, difficulty and breadth are profound and profound. One person's energy and ability are really limited, and can only be selectively studied, researched and applied in combination with actual needs. The level of familiarity is only limited to the scope of his work, and he is also ignorant of many practical applications. In the past, due to the limitations of the conditions, the bloggers also lacked the in-depth research and verification of the combination of theory and practice in the details of the simulation techniques used in their field of work. At present, they are constantly investing in the gradual improvement and summary of instruments and human resources. In the next step, I can write new books and make new contributions to the development of embedded system application technology. Although we already have nearly 30 simulation technology development engineers, from the perspective of development, no matter from the number of talents or the quality of talents, talents in this area are far from enough. More analog technology talents are welcome to join.
