The Foundations of Oscillator Circuit Design is a comprehensive resource written by Guillermo Gonzalez that considers the complete frequency range, from low-frequency audio oscillators to more complex oscillators found at the RF and microwave frequencies. The book gives an understanding of the principles and practice of oscillator circuit design and emphasizes the use of time saving CAD simulation techniques.

Topics range from the theory and characteristics of oscillators, to the design of a wide variety of oscillators (including tuned-circuit, crystal, negative-resistance, and relaxation oscillators).
