ABSTRACT:
A constant voltage generator includes means for compensating for deviations of its output voltage that are due to variations in the supply voltage or changes in ambient temperature. The generator features a negative feedback resistor connected in the emitter circuit of a transistor between whose emitter and collector branches said output voltage appears. A current flows through this resistor which is supplied by another transistor whose current varies as a function of supply voltage variations. The generator may be used for supplying bias voltages to logic circuits.
