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).
