Zen of Analog Circuit Design
RECENTLY UPDATED WITH NEW CONTENT
From 2011 until 2013, I taught a course titled Analog Design for all which lined ideas beginning with MOS transistors and progressed until the design of two-stage amplifiers. The course launched ideas in a way that led the scholar to the synthesis of latest circuits, not merely their evaluation. However I nonetheless felt that there was a extra intuitive technique to introduce Analog Circuit Design, one that may carry out the great thing about the topic in order that the scholar might ‘cease and scent the roses’.
However why a ‘Zen of Analog’…?
As a result of the foundational ideas in Analog carefully mirror human relationships! The aim of this ebook is to take a simplified and intuitive path to unlock some profound secrets and techniques of Analog. The protagonist of this ebook is Ang-Lao, a medieval monk who brings his insights into the Analog world to unravel the challenges in human relationships.
The ebook addresses an issue assertion that a lot of Analog Circuit Design tries to unravel – how do you notice a perfect buffer? It begins with the easy ideas of voltage sources and present sources. From the I-V curve of the MOS transistor, we see the way it behaves very similar to a Voltage managed present supply (VCCS). The inherent problem in getting even a easy two-transistor circuit to work is the battle arising from having two such present source-like parts in collection. The digital inverter is proven to be one such circuit that may operate like an analog amplifier, albeit over a slim vary of enter voltage. The impact of loading on such a circuit is illustrated graphically and is proven as an added problem in getting it to work in an analog method.
Having understood the problems concerned, we see how by the strikingly easy however immensely highly effective idea of suggestions, one of many two transistors will be modified subtly to make it behave like a voltage supply. In that course of, we notice our first approximation to a perfect analog buffer. We then see how manifestations of the identical idea leads us to the synthesis of a complete bunch of two transistor circuits – supply followers, widespread supply amplifiers with gm-load and with diode-connected load, and differential amplifiers . The ideas utilized in synthesis of such elegant circuits are additionally prolonged to the evaluation of far more advanced circuits, for instance, a Voltage to Present (V2I) conversion circuit. We introduce the idea of small sign parameters, gm, gds, displaying the calculations for the acquire and output impedance of our circuits, and quantifying how good every of our buffers actually are.
The narrative switches between ideas of Electronics and the story of Aman-Ra, an engineer from Medieval Egypt. Struggling along with his relationships, his guiding mild is Ang-Lao, who teaches him the key to blissful relationships.
For some, this ebook will sign the top of the worry of Analog. For others, it will likely be the beginning of a love story.

Great book for gaining an intuitive understanding of circuits
Great book for gaining an intuitive understanding of circuits. This has a very different (but welcome) approach. Anyone that has had trouble in the past with understanding how IC chips work should check this book out.

I learned some stuff
Bad things first: this book needs some editing, especially the Kindle edition. The Greek letters in the text did not come through and some of the equations are missing terms. Some material gets repeated ad nauseam, and I’m not really sure I get the entire “Zen” family backstory. The book ends rather abruptly after introducing the concept of compensation to op amps. I wish it continued for a few more chapters.However, I have been an electrical engineer for 35 years and I I’m almost embarrassed to say that I did learn a few things from this book. The book presents a different way of looking at circuits. While reading the book, I frequently said to myself “I never really thought of it that way.” I never thought about a MOSFET inverter as two current sources and how that could make it not so good amplifier..The book is a fairly quick read, and doesn’t get too bogged down with the math. It does a very good job of explaining the front end of an op amp in an intuitive manner.I recommend the boat to people who have a basic understanding of electronics and would like a little more practical knowledge. Any hobbyist or second year engineering student would benefit by putting in a couple hours to read this book.

A fun and relatively quick read
The author takes you step by step through the creation of an operational amplifier in a way that I have never seen in a book. This step by step approach allows you to build each concept up before moving on to the next. He keeps it light and fun, but still gets into some very serious details. Though light hearted in the approach, the material is serious, and is almost guaranteed to leave you with a number of surprising insights into operational amplifier design.

Amusing essay. There are better books.
An amusing essay if you read electronics for entertainment. There are much better books to *understand* electronics even at the intuitive level.There are real “mechanical” problems reading this work on a classic Kindle. Most of the illustrations are too small to see clearly on a Kindle (‘All-new Kindle’). By the time I long-tap and +tap and wait for the Zoom, squint, and go back to text, my thought is lost. Also several illustrations are in color, and classic Kindle is E-ink: monochrome. Red line? Blue line? All grey! One equation is in a strange shadow font and can’t be read easily on Kindle or on PC.The chapter on “Differential Amplifiers” proposes a baffling triplet then in a “flash of genius” proposes a random short. Yes, this does result in the Differential Amplifier… but we got there apparently by accident. Older (1950s-1970s) texts develop the concept more sensibly. Also the small slanted red font on the magic source-line is illegible even on the big color PC.It is very interesting that very complex amplifiers are built without any resistors. This is of course the practice in CMOS (transistors are smaller than resistors), but I like resistors.The technique of relating circuit dynamics to husband/wife dynamics is novel, but would have to be quite different if the topic were resistor-loaded circuits.

It started well
I find the authors suggestion that concepts of analog design to be related to human relationships unpleasant. The author writes well but segues to a human analogy to illustrate this point from time to time. The story line is difficult to follow and distracts from the point. This is not a book I would keep nor want a printed copy of. I have learned some concepts while skipping over the story line, though. The wasted pages might have been better used to explain the math in greater detail.

This book does not rigorously illustrate all the analog circuits. However, will teach you “why”.
This is must read for an analog circuit designer.I am an robotic engineer and my major is mechanical engineering and control.I have studied microelectronic circuit with the books by Professor Sergio Franco.And the Professor Sergio Franco’s book is excellent. However, I cannot gain insight about why the specific circuit is developed.I have read about half of the Zen of Analog Circuit Design. I think that this book will be a good complementary to Sergio Franco’s book.Because this book explains why the specific circuit is made and fabricated.This book does not rigorously illustrate all the analog circuits. However, will teach you “why”.

Most books on Analog Design take an equation based approach leading to clouding the reader’s mind with much that is of little significance. The equations typically contain so many terms that the essential idea behind the equation remains elusive to the lost reader.Let me take a moment to include a quote by Richard Hamming here – ‘The purpose of computation is not numbers; it is insight’.This books is a goldmine of insight. Starting with very simple ideas, the book introduces the reader to progressively more complicated circuits, while building on the ideas presented up to that point. It is a testimony to the writer’s craft and expertise to have written an entire book where all the essential ideas involve just 2 transistors; and yet there is much left to the reader to reflect upon. The writing helps shape the way the reader ought to think about circuits. There is little doubt that the thought process explained in the book, is at some level, what on in the mind of a circuit design expert as they set to analyze/design a circuit.It would not be an exaggeration to say that this is the first Analog design book of its kind. This is the way Analog Design needs to be taught. It gives the reader a peek into the mind of a circuit design wizard. The human-relations angle lends a touch of occasional lightness and does not detract from circuit design which is really the core. I keenly look forward to the rest of the series !

Good book but some problem with Kindle lite app. As I switch to page 37 the app crashes every single time on my oneplus 3T.
