Publication number: 20250211209Abstract: Provided are a duty cycle calibration circuit and method, a chip, and an electronic device. In the duty cycle calibration circuit, through a counting clock signal having a higher clock signal frequency than a calibration clock signal, a counting unit is configured to acquire a number of counting pulses generated in a high-level state and a low-level state of the calibration clock signal within a preset counting period, so as to obtain an actual duty cycle of the calibration clock signal. Compared with a method of acquiring a duty cycle of a calibration clock signal by comparing the calibration clock signal with a reference clock signal, inaccurate measurement of the duty cycle of the calibration clock signal after the reference clock signal is affected can be overcome. Therefore, accuracy of measurement of the duty cycle can be improved, and precision of calibration of the duty cycle can be improved accordingly.Type: ApplicationFiled: August 30, 2022Publication date: June 26, 2025Inventors: Jianyu DING, Yueting LI, Yang YANG, Xu GUO, Yang LIU
