Patent ID: 7880239

Claim:
An electronic circuit, comprising: a field effect transistor comprising: a drain region and a source region having a first conductivity type; a body region formed at least between said drain and source regions, said body region having a second conductivity type other than said first conductivity type; a gate electrode formed above a channel region of said body region, said gate electrode being separated from said channel region by an insulation layer; a doped region located between said drain and source regions and having said first conductivity type; and a body terminal connected to said body region and configured to receive a variable control voltage; and a circuit element connected to said field effect transistor so as to form a combined device having a signal input terminal and a signal output terminal, wherein at least one of said signal input terminal and said signal output terminal is connected to said body terminal and the other of said signal input terminal and said signal output terminal is connected to said gate electrode.
