ABSTRACT:
A reference voltage source, in particular for amplifier circuits, includes a pair of transistors having their bases connected together, one of the transistors being further connected as a diode and the other being operated normally. In the collector circuit of the transistors, a current mirror circuit is connected which includes a further transistor which is connected in series through an additional transistor to a reference potential. The base of the additional transistor is connected with emitter resistors in the emitter circuit of the first-mentioned transistors and the reference voltage is taken off at the connection between the serially connected further and additional transistors. Additional current mirror circuits may be employed for providing a symmetrical operation of the amplifier circuit supplied by the reference voltage source.
