ABSTRACT:
Systems in accordance with the presently claimed invention use input data to create an output pulse that is a fraction of the width of an input pulse. In some embodiments, the invention accepts input data and an input signal that has pulses of a specific frequency. In some embodiments, the invention uses a phase lock loop to create multiple signals of a higher frequency than the frequency of the input signal. Each of these multiple signals is offset by a certain phase from the other signals. In some embodiments, the invention synchronizes the input data to each of these multiple signals. The invention uses the phase difference between the multiple signals to create an output pulse as a function of the input data that is a fraction of the width of the input pulse.
