If you are a fan of Robert Lacoste's The Darker Side column in Circuit Cellular, then you will be happy to know that he has published a book with tips and tricks to help boost your design's performance: Robert Lacoste's The Darker Side: Practical Applications for Electronic Design Concepts from Circuit Cellar. Topics covered span digital signal design to avoiding interference. We are fortunate to have an excerpt for you, from Chapter 4 on oscillators, presented on the RF and Microwave Designline in five parts.

Part 1: Introduction to oscillators, including piezoelectricity and how a crystal works. See Part 1 text here. Part 2: Explains how a crystal is adjusted differently to be used as a parallel resonant frequency versus series resonance. See Part 2 text here. Part 3: Takes a look at a classic quartz-based CMOS oscillator. See Part 3 text here. Part 4: Reviews how to accurately determine oscillator start up time and determine if it is stable. See Part 4 text here. Part 5: Asks/answers the question, what happens at higher frequencies (overtone mode)? See Part 5 text here.
Other chapters in the book cover impedance concerns (Chapter 1), electromagnetic compatibility (Chapter 2), signal processing (Chapter 3), communications (Chapter 5), and power (Chapter 6).
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
