Latest Patents

Haifeng Zhou holds a patent for a charge pump circuit and phase-locked loop. This invention includes several modules such as start, bias, current mirror, charging and discharging feedback control, and charging and discharging matching modules, which are electrically connected in sequence. The start module initiates the bias module, which generates a constant bias current. This current is then amplified by the current mirror module and output in two paths. The feedback control module detects the output voltage of the charge pump and adjusts the current in the matching module to suppress any mismatch between charging and discharging currents. This design allows for matched charging and discharging currents across a wide output voltage range, eliminating the need for an operational amplifier.
