Abstract
In one embodiment, an apparatus is provide with a combinational logic circuit to generate a data input signal; a delay element, coupled to the combinational logic circuit, to provide a delayed data input signal in response to the data input signal. Additionally, the apparatus is provided with a system bistable circuit, coupled to the combinational logic circuit, to generate a system bistable signal in response to at least the data input signal; a shadow bistable circuit, coupled to the delay element, to generate a shadow bistable signal in response to at least the delayed data input signal. Further, the apparatus is provided with an output joining circuit, coupled to the system and the shadow bistable circuits, to provide a data output signal in response to the system and the shadow bistable signals.
