From Wikipedia, the free encyclopedia VBE multiplier (inside grey box) used in push-pull amplifier biasing In electronics, a rubber diode or VBE multiplier is a bipolar junction transistor circuit that serves as a voltage reference. It consists of one transistor and two resistors, and the reference voltage across the circuit is determined by the selected resistor values and the base-to-emitter voltage (VBE) of the transistor. The circuit behaves as a voltage divider, but with the voltage across the base-emitter resistor determined by the forward base-emitter junction voltage. It is…
