ABSTRACT:
A PNP turnaround circuit includes a common base lateral PNP transistor connected to the output of a high gain amplifier having a resistor coupled thereacross. The input is supplied from a differential pair of NPN transistors havng their emitters connected to a current source. One transistor of the differential pair has its collector connected to the collector of the PNP for supplying a push/pull output. In another embodiment the collector of the PNP is returned to ground through a load resistor and a DC level shifted output signal is developed.
