Patent ID: 7598813

Claim:
An amplifier circuitry, the circuitry comprising: first and second n-channel metal oxide semiconductor field-effect transistors (N-MOSFETs), wherein: a gate of the first N-MOSFET is directly connected to a gate of the second N-MOSFET; and a gate width of the first N-MOSFET is less than a gate width of the second N-MOSFET; and an input voltage is provided to the directly connected gates of the first N-MOSFET and the second N-MOSFET; a third N-MOSFET, wherein: a bias voltage is provided to a gate of the third N-MOSFET; a source of the third N-MOSFET is coupled to a drain of the second N-MOSFET; and an output voltage is provided from a drain of the third N-MOSFET; and an inductor that is coupled between the drain of the third N-MOSFET and a power supply voltage.
