Abstract
A circuit includes a transistor having a biased gate terminal and an input coupled to a bulk terminal. A voltage applied between the bulk terminal and the source terminal modulates the drain-source current. The transistor operates in a saturation region with a bias voltage applied to the gate terminal. The output current is received by a load resistor or an active load.
