Abstract
A clamping circuit particularly adaptable for integrated circuits having improved low impedance characteristics. The operating characteristics of a "current-mirror" clamping circuit are improved by coupling a regenerative semiconductor feedback circuit means across the transistor and diode current-mirror circuit for increasing current flow to the semiconductor diode in response to the clamping transistor being driven to a lower impedance state by voltage changes coupled to its emitter terminal.
