To continue the use of standard power supplies and yet reduce on-chip voltage to preserve high reliability of miniaturized circuitry, on-chip voltage conversion is necessary. This circuit provides a regulated reference voltage Vref below the level of incoming supply voltage Vdd. Vref is insensitive to Vdd variation and has quick recovery from voltage perturbations.
