Latest Patents

Wei Deng's latest patents include groundbreaking inventions that enhance the functionality of phase-locked loops. One of his notable patents is the "Divider control and reset for phase-locked loops." This invention describes a phase-locked loop circuit that generates a clock signal using a reference signal. The circuit features a programmable divider stage with multiple divider stages. During frequency calibration, a control circuit generates a pause signal when certain divider stages reach a specific logic state, allowing the programmable divider to maintain that state.

Another significant patent is the "Digital linearization technique for charge pump based fractional phased-locked loop." This apparatus includes an oscillator, frequency divider, phase circuit, charge pump, and filter. The frequency divider generates an early feedback signal and asserts a feedback signal after a set number of clock periods. The phase circuit produces charge and discharge control signals, enabling the charge pump to adjust a circuit node to generate a frequency control signal. The filter circuit then attenuates specific frequency components of this signal, allowing the oscillator to modify the clock signal's frequency.
