Abstract:
1. An integrated circuit, comprising: an amplifier transistor configured to amplify an input signal; a biasing circuit configured to set a bias voltage in such a manner as to allow the amplifier transistor to perform amplification; an electrostatic protective circuit configured to set the bias voltage for the amplifier transistor in such a manner as to make the amplifier transistor to turn off, based on a power supply voltage to be applied to the electrostatic protective circuit; and a switching circuit configured to switch the bias voltage for the amplifier transistor based on a power supply condition, wherein the electrostatic protective circuit includes: the switching circuit is configured to drive the gate of the switching transistor through the first inverter in such a manner as to make the switching transistor to turn off based on a power supply condition.
