Amplifier circuits and methods are implemented using a variety of different embodiments. According to one such embodiment, an amplifier circuit is implemented to amplify a first signal to drive an output load. The circuit has a field-effect transistor (FET) with a gate, a source and a drain. A switch arrangement is coupled to the gate, the source and the drain. State control logic provides state information for a first state and a second state. In the first state, the first switch arrangement connects the first signal to the gate and connects the drain and source to reference voltages. In the second state, the switch arrangement disconnects the first signal from the gate, connects the drain to a voltage supply and connects the source to the output load, thereby causing the FET to operate in source-follower mode.
