ABSTRACT:
An inverter is disclosed which includes a fast turn-on circuit and a turn-off circuit comprising a standby current source and a parallel circuit of a diode and capacitor connected to the input of a bipolar transistor. Standby current plus an input transient applied via the charged capacitor cause high speed turn-on of the bipolar device. The diode having a lower threshold than the bipolar base-emitter diode switches when a turn-off transient is applied to the bipolar device shunting standby current which held the bipolar in the conducting state to ground via the conducting diode.
