Abstract
A device generating a precise reference voltage. This device comprises a semiconductor circuit ( ) of “bandgap” type delivering a reference voltage (Vref) and a multiplier circuit ( ) delivering an output voltage (V ) from the reference voltage. A galvanic link ( ) makes it possible to supply the semiconductor circuit ( ) from the precise reference voltage, and an initialization circuit ( ) makes it possible, on initialization, to replace this precise reference voltage with the build-up voltage of the supply voltage. Application to reference voltage generating circuits of analogue/digital converter circuits in CMOS technology.
