摘要
An analysis is presented in this contribution to describe the steady-state amplitude of a CMOS LC Colpitts oscillator, as well as its response to small interferences. The problem of signal dependency of noise sources is also addressed. The general conclusions of the analysis are applicable to most LC oscillators. The procedure to perform a general analysis for an arbitrary LC oscillator is outlined. Controlled experiments are used to verify each important conclusion for the Colpitts analysis and implications on design are discussed.
