ABSTRACT:
A bipolar input circuit for regulating the current/voltage level at the base of a switching transistor (QA) provides a capacitively-controlled discharge path from the base through a discharge transistor (QC) when an input signal (V.sub.I) makes certain voltage transitions. The base of the switching transistor responds to the voltage at an emitter (E1) of an input transistor (QB) which has another emitter (E2) coupled to the base of the discharge transistor. Its base is further coupled to a capacitor (C) which controls the discharge path.
