Abstract
A circuit for shifting the potential level of an input signal toward higher potentials is added to a conventional differential ECL circuit in order to shift levels of emitter potentials of npn bipolar transistors forming a current switch toward higher potentials. Thus, the ECL circuit is improved to ensure a continuous flow of a current and to maintain stable operations even at an instant where base potentials of the npn bipolar transistors are switched by a standard ECL-level signal even when the power source voltage is around −2 V.
