Viewpoint: Analog Design is Here to Stay

Compiled from Linear Technology’s original application notes, Analog Circuit Design, Volume 2 is quite a handful. That is, it’s at least five pounds and over 1200 pages. The book is co-edited by Bob Dobkin, Linear’s Chief Technical Officer and the late Jim Williams who was a staff scientist at Linear Technology.

This in-depth source book of circuit design solutions supplies engineers with practical design techniques that focus on common analog challenges. The full support package includes online resources such as data sheets, design notes and LTspice® design simulation software tools from Linear Technology.

The last time I reviewed a book I forgot to include the details on how to purchase the book. Then, we got more than a half-dozen calls from people who wanted a copy. I’ll include the information now. This book’s number is: ISBN: 978-0-12-397888-2. It is published by Elsevier Inc., whose website is Pub. Date: December 2012. US Price: $84.95.

Part 1 starts with a section on “Power Management”

Section 1 has separate tutorials covering:

  • Three-terminal regulators

  • Transient response testing

  • 100 A active load

Section 2 is on switching regulator design covering:

  • Dc-dc converters

  • Buck switching regulators

Section 3 is about linear regulator design

Section 4 covers “High Voltage and High Current Applications”

Section 5, “Powering Illumination Devices, ” covers:

  • LCD backlight technology

  • Flash illumination.

Section 6 covers Automotive and Industrial Power Design.

Part 2 is organized into three sections.

Section 1 is on data conversion that includes single cell operation, 16-bit DAC, and testing A/D converters.

Section 2 is “Signal Conditioning” in 14 separate items,  ranging from power buffers to thermal management to  bandpass filters. • Varactor biasing

  • Coupling methods

  • RMS power detectors

Part 3,  “Circuit Collections,” covers the following:

  • Clock sources

  • Measurement and control circuits

  • Video circuit collection

  • Practical circuits for management and control

  • Signal conditioning and power conversion

  • Signal sources, conditioners and power circuitry

  • Current sense circuits

  • Power conversion, measurement and pulse circuits

In the book’s preface, co-editor Bob Dobkin noted, “Analog design is challenging. There are many ways to get from input to output, and the circuitry in the middle can lead to divergent results. Analog design is like learning a language. When you first learn a language, you begin with a vocabulary book and then analyze writings in that language by looking up words one by one as you encounter them. Likewise, in analog design you learn the basics of the circuit, as well as the function of different devices. You can write node equations and determine what the circuit is doing by studying each of the individual circuits.”

Dobkin added, “Today, analog design is in greater demand than ever before. Analog design is now a combination of transistors and ICs that provide high functionality in analog signal processing. This volume focuses on fundamental aspects of circuit design, layout, and testing. It is our hope that the talented writers of these application notes shed some light on the ‘black art’ of analog design.”
