Abstract:
A one-shot circuit, comprising:a one-shot input terminal; a one-shot output terminal; a non-inverting delay element having an input terminal coupled to the one-shot input terminal and further having an output terminal; a plurality of AND circuits coupled in series from a first AND circuit to a last AND circuit, the first AND circuit having a first input terminal coupled to the output terminal of the delay element, and a remainder of the AND circuits having a first input terminal coupled to an output terminal of a previous AND circuit, each AND circuit having a second input terminal coupled to the one-shot input terminal; and an output circuit having a first input terminal coupled to the one-shot input terminal, a second input terminal coupled to an output terminal of the last AND circuit, and an output terminal coupled to the one-shot output terminal, wherein the output circuit comprises: a first pass gate coupled between the one-shot input terminal and the one-shot output terminal and having a control terminal coupled to the output terminal of the last AND circuit; and a pulldown coupled to the one-shot output terminal and having a control terminal coupled to the output terminal of the last AND circuit.
