摘要：
A power supply circuit includes a first power amplifier that amplifies an input signal; a high pass filter that removes frequency components that are lower than a predetermined first cutoff frequency from an output signal of the first power amplifier; a current detector that detects a current value of the output signal of the first power amplifier; a composite signal generation circuit that combines the input signal and an output signal of the current detector; a second power amplifier that amplifies an output signal of the composite signal generation circuit; a low pass filter that removes frequency components that are higher than a predetermined second cutoff frequency from an output signal of the second power amplifier; and a signal output terminal that combines a current of an output signal of the high pass filter and a current of an output signal of the low pass filter and then outputs the resultant signal.
