Title:
CRYSTAL OSCILLATOR CIRCUIT AND METHOD FOR CONTROLLING OUTPUT SIGNAL AMPLITUDE THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/000571
Kind Code:
A1
Abstract:
Disclosed in the present invention is a method for controlling the output signal amplitude of a crystal oscillator circuit, said method comprising: acquiring a current first detection voltage of the crystal oscillator circuit; comparing the first detection voltage with a preset reference voltage, and on the basis of the comparison results, generating a corresponding control signal; by means of the control signal, adjusting the magnitude of the current of the crystal oscillator circuit in order to control the output signal amplitude of the crystal oscillator circuit. Also disclosed in the present invention is a crystal oscillator circuit.
