ABSTRACT:
An improved ECL circuit in which reference voltages have been eliminated is provided. The base of the reference switching transistor which is usually connected to a reference voltage is instead connected to the emitter of an emitter follower transistor coupled to the input switching transistor. The need for a reference voltage is thus eliminated because the emitter of such emitter follower transistor, and thus the base of the reference switching transistor, will be at the opposite level of the input to the base of the input switching transistor.
