Abstract
The present invention relates to an integrated circuit bidirectional switch formed from bipolar transistor devices, in which the saturation voltage is sought to be reduced. More specifically, an integrated NPN bipolar transistor is formed with oxide insulation, and the normal direction of current flow is from the emitter to collector, and an integrated PNP bipolar transistor is formed with oxide insulation, and the normal direction of current flow is from the collector to emitter.
