Abstract
An amplifier may include a plurality of stages, wherein each stage may have an amplifier stage output configured to generate an amplifier output signal and a transistor coupled at its gate terminal to the amplifier input and to the gate terminals of the transistors of the other amplifier stages. Each stage may be configured to periodically and cyclically operate in an amplifier mode in which the amplifier stage generates at its corresponding amplifier stage output a power-amplified version of a signal received at the amplifier input and a in reset mode in which the transistor of the stage operating in the reset mode has an electrical property thereof reset. At any given time, at least one amplifier stage is operating in the amplifier mode. The amplifier may be configured to output as an output signal one of the amplifier output signals corresponding to an amplifier stage operating in the amplifier mode.
