Abstract

An integrated circuit is provided. The integrated circuit includes a plurality of skitter circuits and a multiplexer that provides the waveform to the plurality of skitter circuits. The plurality of skitter circuits includes at least a first skitter circuit and a second skitter circuit. The first and second skitter circuits are arranged in parallel with respect to an output of the multiplexer. The first skitter circuit can include a first data path and a plurality of first inverters on that first data path. Further, the second skitter circuit can include a second data path, a plurality of second inverters on the second data path, and a delay element connected in series with an input of an initial inverter of the plurality of the second inverters on the second data path.
