1. A circuit comprising:
- a chain of inverters operable to produce a first delayed version of an input signal and a second delayed version of the input signal;
a first subcircuit configured to receive the first delayed version of the input signal and coupled to an output terminal;
a second subcircuit comprising a first pulse generator operable to generate a rising output transition at the output terminal responsive to a falling transition of the input signal, wherein the first pulse generator is further operable to access the input signal and the second delayed version of the input signal; and
a third subcircuit comprising a second pulse generator operable to generate a falling output transition at the output terminal responsive to a rising transition of the input signal, wherein the second pulse generator is further operable to access the input signal and the second delayed version of the input signal.
