摘要： A communication system is provided and includes a current control circuit, a processing module, and a detection circuit. The current control circuit has an output node. The current control circuit is capable of drawing input current to the output node. The processing module is capable of operating according to a current accumulated at the output node and an output voltage at the output node. The detection circuit is capable of detecting the output voltage and controlling the processing module according to a detection result of the detection circuit. When the detection circuit detects that the output voltage is lower than a threshold, the detection circuit is capable of controlling the processing module to decrease an output power of a power amplifier or to decrease an operating frequency of a processor.

摘要： A series-parallel resonant matching circuits and a broadband power amplifier thereof are disclosed. The series-parallel resonant matching circuit is connected to the last power transistor and the next power transistor. The series-parallel resonant matching circuit comprises a series matching inductor, a parallel matching inductor and an impedance transformation unit. The impedance transformation unit is connected between the series matching inductor and the intrinsic parallel matching inductor for transforming impedance. The parallel matching inductor and the parallel capacitor of a last level power transistor constitute a LC parallel resonant circuit, the series matching inductor and the series intrinsic capacitor of a next level power transistor constitute a LC series resonant circuit. Besides, the intrinsic parallel capacitance is a drain-to-source capacitor for the power transistor. The intrinsic series capacitance is a gate-to-source capacitor for the power transistor.
