Low noise oscillators

Abstract

The author describes a set of design rules which are general and can be used to produce oscillators with a very low noise performance where both additive and flicker noise are considered. Linear theories which accurately describe the noise performance of resonator-type oscillators are presented. The limits set by varactor diodes on the noise performance are described and the noise degradation caused by open-loop phase error is shown. Seven design examples are demonstrated which show close correlation with the theory.<>
