Abstract
A circuit for switching between supply voltages and in particular for non-volatile flash memory devices and of the type comprising a first and a second circuit branch each incorporating a pair of transistors connected in series provides that at least one branch of the circuit be structured with a bridge circuit made up of P-channel MOS transistors. The bridge is made of a first and a second pairs of transistors connected between a first supply voltage reference and a common node. The first pair comprises transistors bigger than the transistors of the second pair while between the transistors making up the second pair is inserted a pair of resistors. Between the pair of resistors there is an interconnection node connected to a corresponding interconnection node between the transistors of the first pair.
