Abstract:
1. A power amplifier circuit that applies an output voltage according to a given input voltage to a load, comprising: an amplifying section that outputs the output voltage according to the input voltage, an output port of the amplifying section being connected to the load, the amplifying section including a source-side Zener diode for generating a constant voltage and a sink-side Zener diode for generating a constant voltage; a source-side power source path that supplies an electric current output from the amplifying section via the output port to the amplifying section; a sink-side power source path that supplies an electric current drawn from the amplifying section via the output port to the amplifying section; a source-side capacitor that is connected between the output port of the amplifying section and the source-side power source path; and a sink-side capacitor that is connected between the output port of the amplifying section and the sink-side power source path.
