Title:
CLOCK GENERATOR CIRCUIT AND CLOCK SIGNAL GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/206075
Kind Code:
A1
Abstract:
Disclosed are a clock generator circuit and a clock signal generation method. The method comprises: using a direct current bias circuit in a first clock source, superimposing a first direct current voltage on a first clock signal output by a first oscillator circuit, so as to generate a second clock signal; and performing a logical operation on the second clock signal and a third clock signal generated by a second clock source, so as to generate a fourth clock signal. The fourth clock signal serves as an output signal of the clock generator circuit. The method of the present invention enables a clock generator circuit to continue externally outputting a correct clock signal when a first oscillator circuit cannot operate normally, thus avoiding clock signal interruption during a switching process from a first clock source to a second clock source.
