Title:
OSCILLATOR, INTEGRATED CIRCUIT, TIMING CHIP, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/028595
Kind Code:
A1
Abstract:
An oscillator, an integrated circuit, a timing chip, and an electronic device. The oscillator comprises a bias circuit (100) and a current mode comparator (200). The bias circuit (100) is connected to the current mode comparator (200). The bias circuit (100) is configured to generate a bias current and a bias voltage, the bias current being used to supply power to the current mode comparator (200). The current mode comparator (200) is configured to receive the bias voltage and use the bias voltage as a reference voltage for comparison with an input voltage to generate a pulse signal. The current mode comparator (200) can share a bias voltage of the bias circuit (100) and use the bias voltage as a reference voltage, thereby avoiding the need for providing a reference voltage by a dedicated reference voltage generating circuit, reducing the number of branches of a circuit, and further effectively reducing power consumption and cost.
