Latest Patents

Shewell's notable patent is titled "Methods and devices for testing the operation of counters used in phase-locked loops." This invention addresses the issue of intermittent miscounts generated by counters in a phase-locked loop (PLL). The method involves precisely measuring these miscounts by detecting changes to a predetermined waveform, such as a sawtooth waveform. The detection is achieved using an open loop setup, which consists of two separate signal generators feeding distinct frequencies into the MAIN and REF counters of a PLL. By slightly offsetting the frequencies and integrating an output, the predetermined waveform is generated. Miscounts can then be detected by comparing the waveforms corresponding to miscounts with theoretically predicted, predetermined waveforms.
