Reading notes on "Operational Amplifier Parameter Analysis and LTspice Application Simulation" [Copy link]

This is my first time writing a short review, so I’ll just ramble on a bit.

I thought I would receive it before the holiday (October 1st). I didn’t dare to go out during the holiday because there were too many people and the weather was too hot. I stayed at home and it was very comfortable.

Wouldn't it be wonderful to read a new book? However, I didn't receive the book before the holiday, which was disappointing.

After the holidays, the company was busy, so I didn't have time to go to the concierge to check if the books had arrived, and the courier didn't notify me.

As a result, I didn't receive it for a few days, and then I went to check a few days later, and it arrived, maybe it had already arrived a few days ago.

I opened the package and found the book was new, plastic-wrapped and in good shape. The title page of the book was a promotional poster for the cooperation between ADI and Shijian.

Color pages. I first scanned the table of contents and preface. As the title suggests, the application of amplifiers is centered around parameters. Chapter 5

This is an introduction to LTspice. I have never used LTspice before. This software is the simulation software of Lingte. Lingte is in power supply

The achievement of the product is quite remarkable. This software is a free professional spice simulation, compared with those with node restrictions

The free spice is much better, it is really a blessing from heaven, except for the Dao version of software.

This is a book for engineers, a very practical book.

I have not worked in this field since I started working, and I have no experience in precision electric control. I have no experience in resistors below 0.01%.

I have never used it before. This book will definitely make up for my shortcomings. Thanks to EEworld and the author.

Today I will speak my mind freely , sincerely, thanks.

Why hasn't it arrived in so long? We sent it out before the holidays, how could it have been stuck on the road for so many days?

This book is good, and this software is also good! It's a pity that I didn't catch up with the review!

It is really not easy to take the time to read and understand the whole book.

Yes, it is a very good book, a very practical book

Yes, the National Day is a little regretful, haha

I agree

Keep writing your review :-)

The first chapter is about the basics of op amps, which is basically the content of the analog circuit textbook, but it is very concise.

The author emphasizes the differences between practice and theory and describes several types of computational circuits.

This chapter is relatively short, but it feels concise and concise. In particular, it compares magnification to a mechanical lever.

This is something I haven't seen before and is more friendly to beginners.

The focus of this book is Chapter 2, Parameters, which is about the actual design that revolves around parameters.

Continue next time.

Best regards, thanks!

As it was the end of the year, the company's busiest time, the review article was inevitably delayed.

The first chapter briefly introduces the basic content of the circuit principle: "Kirchhoff's law",

'Superposition theorem', 'Thevenin theorem', indeed, this is the most basic principle of circuits and

Methods, core ideas. Then there are typical circuits of OP circuits, addition, subtraction, integration, etc.

The complaint is that the spice of LT is a bit difficult to use, maybe I am not familiar with it.

Roll, the result is shrinking, I'm not used to it, PADS AMS, orcad, are not all

Zoom in. And I can't select by single-clicking. It's very difficult to select a component. I don't know where to start.

Right-clicking is quite user-friendly. You don’t need to select it. Just move the mouse over it and right-click to display the properties.

Moving and deleting are very difficult. Wires are also a bit strange. Moving them can actually break the wires.

I'm also impressed. I simulated a Schmitt trigger, which feels pretty good :-) After all, a

Powerful circuit simulation software can be free, which is a great achievement :-)

My feeling is that all of them charge fees when there are more than 50 nodes, except for the harmonious version :-)
