ABSTRACT:
An amplifier includes: a FET having a source electrode, a drain electrode and a gate electrode, wherein an input signal input to the gate electrode is amplified by the FET and an output signal indicating the amplified input signal is output from the drain electrode; a first voltage biasing unit, coupled to the source electrode of the FET, for biasing the source electrode at a preset positive potential; and a second voltage biasing unit, coupled to the gate electrode of the FET, for biasing the gate electrode at a potential lower than the potential of the source electrode during the operation of the FET.
