Investigation of oscillation stability area for dualmode crystal oscillator by means of computer spice simulation

Abstract

In the given paper the effective simulation technique of quartz oscillators the in time domain with use of general purpose EDA software (PSPICE, MicroCAP, etc) is offered. The main idea is reception of averaged on the first harmonic parameters of nonlinear active part of self-oscillating circuit with the help of widespread programs of circuit simulation, with the subsequent analysis of complete self-oscillatory circuit by analytical methods. Detailed procedures both analysis of single and dual-mode crystal oscillators with use of MicroCAP 6 program are given
