Abstract
The selector circuit is particularly well suited to the switching over of two voltages VPP1 and VPP2, greater than the supply voltage Vcc of an integrated circuit without a priori knowledge of which of the two voltages is the highest. The selector circuit includes first and second switch circuits coupled by first and second MOS transistors whose well is biased by the output voltage of the selector circuit.
