SPICE simulation of high-Q crystal oscillators: single and dual-mode oscillator analysis

摘要

In the given paper the effective simulation technique of quartz oscillators in time domain with use of general purpose EDA software (PSPICE, MicroCAP, etc) is offered. 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 of analysis of single and dual-mode crystal oscillators with use of MicroCAP 6 program are given.
