Title:

LOW-POWER-CONSUMPTION OSCILLATION STARTING CIRCUIT OF CRYSTAL OSCILLATOR, AND CHIP AND ELECTRONIC DEVICE

Document Type and Number:

WIPO Patent Application WO/2023/143488

Kind Code:

A1

Abstract:

Disclosed in the embodiments of the present application are a low-power-consumption oscillation starting circuit of a crystal oscillator, and a chip and an electronic device. The circuit comprises a bias circuit, a drive circuit and a crystal oscillator generation circuit, wherein an output end of the bias circuit is connected to a first input end of the drive circuit, a second input end of the drive circuit is connected to an output end of the crystal oscillator generation circuit, and an output end of the drive circuit is connected to an input end of the crystal oscillator generation circuit; the bias circuit is used for providing a working voltage for the drive circuit; and the drive circuit is used for converting a first clock signal into a second clock signal, the first clock signal is a clock signal generated by the crystal oscillator generation circuit, the second clock signal is a reverse clock signal of the first clock signal, and the amplitude of the second clock signal is directly proportional to the value of the working voltage. In the present application, a relatively small working voltage is provided for a drive circuit by means of a bias circuit, thereby reducing the amplitude of a clock signal, thus reducing the power consumption of an oscillation starting circuit of a crystal oscillator, reducing the standby power consumption of an electronic device, and prolonging the standby time of the electronic device.
