Latest Patents

Xu Guo's latest patents include a duty cycle calibration circuit and method, chip, and electronic device. This invention provides a duty cycle calibration circuit that utilizes a counting clock signal with a higher frequency than the calibration clock signal. The counting unit acquires the number of counting pulses generated during the high-level and low-level states of the calibration clock signal within a preset counting period. This method overcomes inaccuracies in measuring the duty cycle caused by reference clock signal interference, thereby improving measurement accuracy and calibration precision.

Another notable patent is the clock signal noise reduction device and noise reduction method, along with a multi-phase delay phase-locked loop. This device includes a phase generator that produces a multi-phase clock signal based on an input signal. The phase selector selects a channel of the multi-phase clock signal and assigns a delay to the clock signal of the selected channel. The frequency divider then performs fractional frequency division on the delayed multi-phase clock signal, enhancing the overall performance of electronic devices.
