Abstract

A quantitative estimation of the influence of an active device operational mode on the phase fluctuations in precision voltage controlled crystal oscillator at frequency range 100 MHz had been made. The relations between the coefficient of amplitude to phase noise conversion and the ratio of the device linear mode realm to the non-linear mode realm are evaluated. The recommendations obtained with the help of numerical analysis have allowed us to optimize operation of the precision voltage controlled crystal quartz oscillator, and to obtain short-term frequency stability close to the stability of a non-controlled oscillator
