ABSTRACT:
A wideband amplifier having an amplifier input terminal and an amplifier output terminal includes at least one transistor coupled to the amplifier input terminal and an impedance element coupled between the amplifier input terminal and the amplifier output terminal. A feedback signal is transmitted between the amplifier output terminal and the amplifier input terminal by way of the impedance element wherein the feedback signal varies in accordance with changes in an impedance of the impedance element so as to peak a frequency response of the amplifier.
