Abstract
A VLSI chip is disclosed having reduced power dissipation. This is accomplished by limiting the output voltage swing at the output of off chip driver circuits by utilization of a control circuit to regulate the gate bias voltage of an NFET pull-up transistor coupled to the output of the driver circuit and by feeding back the output of the driver circuit to the control circuit.
