Reducing the Precision Oven-Controlled Quartz Crystal Oscillators Warm-Up Time

In this paper the problem of reducing the readiness time of precision oven-controlled crystal oscillators with distributed piezoelectric element heater is considered. This problem has been studied by using the temperature field simulation of internal heating resonator in warming up mode taking into account the effect of design factors. The simulation allows to achieve the oscillator warm-up time of 15 seconds in wide operating-temperature range.
