ABSTRACT:
An ECL circuit with a bias circuit is provided which tracks the gain and operating characteristics of other transistors in an integrated circuit. The bias circuit employs the bandgap reference voltage, V.sub.CS, as the power source. By a transistor and resistor network a bias circuit voltage is generated. The bias circuit is useful in providing a bias to the base of a dynamically switchable low drop current source useful in ECL circuits.
