Abstract
A driver stage formed in integrated MOS technology has a large output signal ratio but with reduced idle currents. First and second control stages are provided of MOSFETs series connected and with their outputs between the MOSFETs connecting to respective gates of an output stage also comprised of series connected MOSFETs. In the output stage, one of the MOSFETs has its channel resistance reduced and is parallel-connected with an additional MOSFET. A boot strap capacitor connects between a gate of the additional MOSFET and an output of the circuit.
