Abstract
Use of a closed loop APC may involve a problem of cost and power consumption due to increased circuit scale. The semiconductor device includes a power amplifier that amplifies an output from a transmission circuit and a regulator that supplies power to the power amplifier. The regulator includes an operational amplifier comprising a loop gain control circuit and a loop gain control voltage generation circuit that supplies control voltage to the loop gain control circuit. The loop gain control voltage generation circuit minimizes a loop gain of the operational amplifier when starting up the regulator.
