Abstract: A charge pump circuit and phase-locked loop include start, bias, current mirror, charging and discharging feedback control, and charging and discharging matching modules, which are electrically connected in sequence. The start module starts the bias module. The bias module generates constant bias current and outputs same to the current mirror module, which receives and amplifies the bias current for output in two paths. The charging and discharging feedback control module detects the output voltage of a charge pump and controls, according to feedback of the output voltage, the current in the charging and discharging matching module, to suppress the mismatch between charging and discharging currents. The charging and discharging matching module receives an external charging or discharging control signal, to charge or discharge the output load of the charge pump. Charging and discharging currents can be matched within a wide output voltage range, without an operational amplifier.
