Abstract

The effect of "sleeping sickness" in crystal oscillators is associated with the low drive excitation after a long storage when the crystal resonator losses become large and nonlinear. In our work we have experimentally shown that specific approximation fits reasonably well towards drive level dependence (DLD) of the crystal resonator losses, if to start measuring from the noise floor and then gradually increase the piezoelectric current up to the normal drives. Here, the dynamics of the mean signal amplitude of the crystal oscillator with the nonlinear resonator and low drives, is presented
