Abstract
A method includes forming a power control circuit through coupling a gate switch array between a buffer stage at an input of the power control circuit and an amplifier array including N amplifier stages in parallel to each other, with N>1. The method also includes coupling each of the N amplifier stages to a corresponding gate switch of the gate switch array, and controlling an output power of the power control circuit by switching one or more appropriate gate switches of the gate switch array to apply an input signal from the buffer stage to a corresponding one or more amplifier stages coupled to the one or more appropriate gate switches such that a maximum output power is achieved when all of the N amplifier stages are turned on and a minimum output power is achieved when only one amplifier stage is turned on.
