Linear Circuit Design Handbook - Hank Zumbahlen

Linear Circuit Design Handbook, edited by Hank Zumbahlen (Newnes, 2008), bridges the gap between circuit component theory and practical circuit design. Effective analog circuit design requires a strong understanding of core linear devices and how they affect analog circuit design.

Linear Circuit Design Handbook – Hank Zumbahlen

This book provides complete coverage of important analog devices and how to use them in designing linear circuits, and serves as a useful learning tool and reference for design engineers involved in analog and mixed-signal design.

Walt Jung - OpAmp Applications Handbook

Comprises Op Amp Basics, Specialty Amplifiers, Using Op Amps with Data Converters, Sensor Signal Conditioning, Analog Filters, Signal Amplifiers, Hardware and Housekeeping Techniques, and Op Amp History.

Walt Jung - OpAmp Applications Handbook

In the past several years, many advances have been made in operational amplifiers and the latest op amps have powerful new features, making them more suitable for use in many products requiring weak signal amplification, such as medical devices, communications technology, optical networks, and sensor interfacing.

Walt Jung - OpAmp Applications Handbook

Walt Jung, analog design guru and author of the classic IC OP-Amp Cookbook (which has gone into three editions since 1974), has now written what may well be the ultimate op amp reference book.

As Jung says, “This book is a compendium of everything that can currently be done with op amps.” This book is brimming with up-to-date application circuits, handy design tips, historical perspectives, and in-depth coverage of the latest techniques to simplify op amp circuit designs and improve their performance.

Analog Dialogue: Analog Devices

See Application Notes too on Amplifiers and Comparators, Current Sense Amplifiers, Differential Amplifiers, Instrumentation Amplifiers, Isolation Amplifiers.

Successful PCB Grounding - Mark Fortunato

This tutorial discusses proper printed-circuit board (PCB) grounding for mixed-signal designs. For most applications a simple method without cuts in the ground plane allows for successful PCB layouts with this kind of IC.

Successful PCB Grounding - Mark Fortunato

"Ground Is Not an Equipotential - At this point it is important to understand that a ground plane, despite what we were taught it EE101, is not an equipotential. First of all, no matter how thick the copper is for your ground plane, it does have resistance. Therefore, if the analog and digital return currents (or any two currents) share a portion of the ground plane (i.e., their currents flow through the same metal) there will be crosstalk between the two as the copper resistance causes IR voltage drops."

Successful PCB Grounding - Mark Fortunato

"With the basics of current flow on a PCB understood, we can start using this knowledge to properly handle the grounding of mixed analog-digital ICs. Ultimately, the goal is to ensure that the digital and analog currents do not share portions of the same return path."

"Many problems with mixed-signal PCB design can be avoided by following this simple advice: pay attention to where the current flows. For most cases all we have to do is remember two basic principles: DC and low frequencies flow mostly in the straight-line path of least resistance between source and load; and high-frequency signals follow the path of least impedance, which is directly under the signal trace. In-between frequencies flow by both paths and in between the two paths."
