Abstract

Analytical expressions for the PM noise in FET oscillators are derived in terms of the FET equivalent circuit elements and the passive circuitry. Efficient methods to reduce the PM noise in fundamental and in harmonic mode are suggested and implements. The effects of the different FET equivalent circuit parameters on large-signal, small-signal, and noise behaviour of FET oscillators are thoroughly investigated. Finally, the effects of harmonic signal on both fundamental and harmonic output noise are determined.
