ABSTRACT:
A reference voltage source comprises a bridge network including two zener diodes and two resistors, two operational amplifiers and two switches whose inputs receive a control voltage from the source and whose outputs are coupled to non-inverting inputs of respective operational amplifiers. The first operational amplifier has its inverting input and its output coupled respectively to the anode and cathode of the first zener diode, while the second operational amplifier has its inverting input and its output coupled respectively to the cathode and anode of the second zener.
