Title:
CRYSTAL OSCILLATOR AND CONTROL CIRCUIT THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/152769
Kind Code:
A1
Abstract:
A crystal oscillator and a control circuit thereof, the control circuit comprising: a peak value detection unit (1005), for detecting the peak value of an oscillation signal of an oscillation circuit (1004) of the crystal oscillator; a voltage control unit (1003), for generating a drive signal according to the peak value of the oscillation signal of the oscillation circuit (1004) and a reference signal, the drive signal being used for enabling the oscillation circuit (1004) to start oscillating and enter an oscillation stabilization phase, and the amplitude of the drive signal decreasing after the oscillation circuit (1004) entering the oscillation stabilization phase, such that the oscillator can start normally, and then enter the oscillation stabilization phase.
