Abstract: Diodes having long minority carrier lifetimes are connected between active switching elements in a monostable or astable regenerative switching circuit. When the circuit is in one state, a forward current flows through the diode, and charge is stored near the junction thereof. When the circuit is triggered to its other state, current through the diode is reversed and the diode acts as a voltage clamp to maintain one of the switching elements in a nonconductive state.

Abstract: A regenerative switching circuit having two active switching elements uses the charge storage and current limiting capabilities of a PN junction to perform the switching and timing functions. When the circuit is in one state, a forward current flows through a PN junction associated with one of the switching elements, and charge is stored near the junction. When the circuit is switched to its other state, a reverse current flows through the junction for a predetermined period until the stored charge is depleted, whereupon the current is blocked and the circuit reverts to its original state.
