Abstract

According to an exemplary embodiment, an amplification module includes a power control circuit. The amplification module further includes a power amplifier coupled to the power control circuit and configured to draw a supply current and receive a supply voltage from the power control circuit. The power control circuit is configured to control a DC power provided to the power amplifier by controlling a product of a sense current, which is a mirror current of the supply current, and the supply voltage. The power control circuit includes a feedback voltage that corresponds to the product of the sense current and the supply voltage. The power control circuit further includes an analog multiplier circuit configured to receive the sense current and the supply voltage and generate the feedback voltage. The power control circuit further includes a differential error amplifier configured to compare the feedback voltage to a control voltage.
