Abstract
A drive circuit includes a first drive transistor coupled between a first supply node and an output pad of an integrated circuit and a second drive transistor coupled between a second supply node and the output pad. The first drive transistor and second drive transistors are controlled by a control signal. A body bias generator circuit is configured to apply a variable first body bias to the first transistor and a variable second body bias to the second transistor. The variable first and second body biases are generated as a function of the control signal and a voltage at the output pad.
