ABSTRACT:
An output driver including pull-up and pull-down output transistors is formed in a silicon substrate. The source and the drain of the pull-up output transistor are formed in a common bulk region of the substrate. A bulk potential control circuit for controlling the voltage of the bulk region, a resistive element and a gate drive control circuit are also formed in the silicon substrate. A layer of interconnect formed over a top surface of the silicon substrate may selectively couple into the output driver circuit one or more of the resistive element between a source of the pull-down output transistor and a reference voltage source, the bulk potential control circuit to control the voltage of the bulk region of the silicon substrate, and the gate drive control circuit to control the rate of change of voltage on the gate of the pull-down transistor as a function of the voltage on this gate.
