Abstract

An input signal is amplified into an output signal that is to be applied to an electrical load including a capacitive component. An amplifier stage includes a pre-amplifier module to receive a first supply voltage, and an output module to receive a second supply voltage. The pre-amplifier module includes a first gain block to pre-amplify the input signal into a first pre-amplified signal, and a second gain block to pre-amplify the input signal into a second pre-amplified signal. A feedback block feeds back the output signal as a feedback signal. A combination element combines the first pre-amplified signal and the feedback signal into a combined signal. The output module combines the combined signal and the second pre-amplified signal into the output signal.
