Claim:
1. A semiconductor device, comprising: a four terminal transistor that is fabricated on a substrate, the transistor comprising: a switch with a first switch terminal connected to the body terminal and a second switch terminal connected to a reference potential node, a closed condition and an open condition of the switch being controlled by a control signal to provide a first operating characteristic in the transistor by connecting the body terminal to the reference potential node when the switch is closed, and to provide a second operating characteristic in the transistor by disconnecting the body terminal from the reference potential node when the switch is open, wherein: the switch comprises an inductor operatively connected between the switch and the reference potential node, the inductor configured to cause the body region to float relative to AC and to connect the body region to the reference potential relative to DC, the first operating characteristic comprises a reduction in a leakage current between the first terminal and the second terminal, and the second operating characteristic comprises an increase of a power added efficiency (PAE) of the transistor.
