| Zusammenfassung: | A solution for amplifying an input signal (Vin) into an output signal (Vo) to be applied to an electric load comprising at least one capacitive component (Cl) is proposed. A corresponding amplifier stage comprises a pre-amplifier module (305) adapted to receive a first supply voltage and an output module (310) adapted to receive a second supply voltage. The pre-amplifier module comprises: a first gain block (315) adapted to pre-amplify the input signal into a first pre-amplified signal, a second gain block (320) adapted to pre-amplify the input signal into a second preamplified signal, a feedback block (325) adapted to feed-back the output signal into a feedback signal, and a combination element (330) adapted to combine the first pre-amplified signal and the feedback signal into a combined signal, and wherein the output module is adapted to combine the combined signal and the second pre-amplified signal into the output signal. |
