ABSTRACT:
A bias generator for use in CML gate circuits provides an output reference voltage that is substantially independent of variations in supply voltage over a wide temperature range. The bias generator includes a temperature and voltage compensating circuit portion which is formed of an emitter resistor and a diode-connected transistor. The emitter resistor is used to control the output reference voltage for the lower temperatures and the base-emitter voltage of the transistor determines the output reference voltage for the higher temperatures.
