How to learn analog circuits, how to learn analog circuits well

To grasp a main line, that is, the unit circuit, the basic co-emission, co-base, co-set. respective structures, gains, input and output impedances. This leads to its characteristics and range of applications.

Then learn according to the function, that is, the input stage (constant current source, constant voltage source - > differential circuit), the intermediate amplification stage (co-ejection), the output stage (power amplifier), and the protection stage.

The other piece is signal generation, signal processing (filter), negative feedback (stability to improve performance), amplitude-frequency and phase-frequency relationship (to judge whether it is stable or not).

There are three major parts of mold electricity.

The ultimate in modular electricity is to draw UA741 by yourself. Haha,The above words are my collection and prepare to review the mold electricity again.,After the study, I have been exposed to more knowledge of digital electricity.,The mold electricity is almost forgotten.,I shared it with you.,I hope it will help you.。

I feel that the analog circuit is such a thing, because I don't feel difficult when I learn the basics, but I still feel very difficult to actually do the circuit, for example, the amplifier in the analog circuit is very simple, but there will be a lot of problems when I actually do it, such as signal interference, zero drift, bandwidth is too narrow, etc., these are strengthened in the actual process, so the foundation must be there, and then we have to do it more, just like many books are considering the ideal situation, but the reality is the reality, It must be done in the actual environment to improve, a signal interference involves a lot of problems, to power decoupling, grounding separation, good wiring, etc., I hope that the landlord has improved in learning and practice.

"Fundamentals of Analog Electronic Technology" is an important professional basic course for electronics and communication majors, but many students face a lot of learning problems at the beginning of school, and some teachers often ignore some problems that should be emphasized, which makes students feel that it is more difficult to learn analog circuits and is very blind. In addition, the content of this course is more than the enlightenment, and it is difficult for many domestic textbooks to be explained in exquisite and nuanced ways, and many writers often do not give the whole book a unified theme, which makes the content seem redundant.

1. From the immaturity of the resistor era to the maturity of the semiconductor era

At the beginning of the general textbook, we talk about some knowledge of semi-conductive group physics, so that everyone can understand the physical process of diode and transistor, and I believe that most students can still understand this part of the content.

2. Get out of the "shadows" of linear circuit analysis methods

Analysis methods available for any circuit: KCL, KVL, Nodal Voltage Method, Linear Circuit Analysis Methods: Superposition Principle, Thevenin, Norton.

Do more questions and do real questions.

Some netizens recommended Mr. Yan's course, and here is a copy of the teacher's latest postgraduate examination circuit information to share with you;

Extraction code: Y273 Mr. Yan Yi made an accurate analysis and explanation of the test center, examination direction, and examination methods of the circuit entrance examination, and pointed out the direction and method for the circuit examination examination, which is worthy of every circuit graduate student's collection and learning;

If you have any questions about resources, please feel free to ask.

Do more questions, analyze more, first analyze the example questions in the book clearly, and then find some other topics to practice. I won't tell you that after I hung up on the mold electricity, it was this method that made the mold electricity performance worse.

Do it often, adjust the circuit, solve a few problems, and take it slowly!

If it's just for the exam, just memorize a few classical circuits and their conventional solutions.

1. Start from the textbook, grasp the knowledge of the textbook, grasp the key points of each chapter to learn, do not memorize, master the method of learning, such as the design of transistor elements in analog circuits.

2. Seek the help of teachers and friends around you, if there are classmates around you to learn analog circuits, you can study with him, ask each other for advice if there is a place, and actively ask the teacher at the same time.

3. Learn analog circuits, the most important leakage bend is to learn more and do more, if possible, conduct more circuit experiments, learn from practice, and grope forward in the process of designing their own boring circuits, you can achieve better results.

4. Go to the relevant power plant for practical learning.

5. Zen Brigade must have perseverance and patience.
