Abstract: Embodiments of the present disclosure include a harmonic power amplifying circuit with high efficiency and high bandwidth and a radio-frequency power amplifier. The circuit comprises an input matching network (11), a transistor (M), and an output matching network (12); a gate of the transistor (M) connected to an output end of the input matching network (11), a drain thereof connected to an input end of the output matching network (12), and a source thereof being grounded; wherein the output matching network (12) enables a lower sideband of the harmonic power amplifying circuit to work in a continuous inverse F amplification mode and an upper sideband of the harmonic power amplifying circuit to work in a continuous F amplification mode; wherein the output matching network (12) and a parasitic network of the transistor (M) form a low pass filter. By transitioning from the continuous inverse F power amplifier working mode to the continuous F power amplifier working mode, the efficiency of a continuous harmonic control power amplifier is effectively improved to be higher than 60%, a relative bandwidth is improved to be higher than 80%, and the harmonic impedance is simple to match and easy to realize.

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.
