Abstract:
A power amplification circuit includes: a first amplifier that is input with a first signal and outputs a second signal; a bias circuit that supplies a bias current or voltage to the first amplifier; and a control voltage generating circuit that generates a control voltage in accordance with the first signal. The bias circuit includes a first transistor that outputs the bias current or voltage, a second transistor provided between the emitter or source of the first transistor and ground, and a third transistor that is supplied with the control voltage and that supplies a first current or voltage to the second transistor. The value of the first current or voltage when the signal level is a first level is larger than the value of the first current or voltage when the signal level is a second level. The first level is higher than the second level.

Claim (Index 1):
A power amplification circuit comprising:\n a first amplifier that is input with a first signal and outputs a second signal obtained by amplifying the first signal; a bias circuit that supplies a first bias current or a first bias voltage to the first amplifier; a control voltage generating circuit that generates a first control voltage and a second control voltage; and a second amplifier stage that amplifies the second signal and a second bias circuit that supplies a second bias current or a second bias voltage to an amplifier of the second amplifier stage, wherein the control voltage generating circuit includes:\n a second amplifier that is input with the first signal and outputs a third signal obtained by amplifying the first signal, and \n a voltage outputting circuit that outputs the first control voltage in accordance with the third signal, and that outputs the second control voltage in accordance with a signal level of the first signal, and \n wherein the first bias current or the first bias voltage is based on the first control voltage, and the second bias current or the second bias voltage is based on the second control voltage.
