ABSTRACT:
A reference voltage source comprises a bridge circuit having two avalanche diodes in a first pair of opposite arms and two resistors in a second pair of opposite arms, as well as two operational amplifiers, An AC-DC voltage converter has its input connected to an output terminal of the source. A voltage comparator have inputs connected to the output of the AC-DC voltage converter and the output of a DC voltage setting circuit. The output of the comparator is connected to the non-inverting input of one of the operational amplifiers.
