Abstract:
1. An amplifier, comprising: an input terminal; a first transistor of a first conductivity and a second transistor of a second conductivity, each transistor comprising a source terminal, a gate terminal and a drain terminal respectively, the source terminal of the first transistor being coupled to the source terminal of the second transistor, and the gate terminal of the first transistor and the gate terminal of the second transistor being coupled to the input terminal; an output terminal coupled to the drain terminal of the first transistor and the drain terminal of the second transistor; further comprising a first depletion capacitor coupled between the gate terminal and the source terminal of the first transistor; further comprising a first bias voltage input terminal adapted to provide a first bias voltage to the gate terminal of the first transistor; wherein the first bias voltage input terminal is provided between the negative terminal of the first gate capacitor and the positive terminal of the first depletion capacitor.
