Input circuit for producing discharge path to enhance operation.

摘要

A bipolar input circuit for regulating the current/voltage level at a control electrode of an electronic component (QA) provides a capacitively-controlled discharge path from the control electrode through a discharge transistor (QC) when an input signal (V,) makes certain voltage transitions. The control electrode responds to the voltage at an emitter (E1) of an input transistor element (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.
