Latest Patents
One of his latest patents is titled "Method and apparatus for Vernier ring time to digital converter with self-delay ratio calibration." This invention provides a method and apparatus for a Vernier ring time-to-digital converter that utilizes a single clock input and an all-digital circuit. It calculates a fixed delay relationship between a set of slow buffers and fast buffers. The method for calibrating a Vernier Delay Line of a TDC involves inputting a reference clock to both slow and fast buffers, determining the delay ratio, and adjusting it to a fixed value using an up-down accumulator to generate control signals.
Another significant patent is the "Digital phase locked loop." This adaptive digital phase-locked loop includes a digital configurable phase detector that receives a reference signal and a feedback signal. It generates a detection signal indicative of the phase/frequency difference between these signals. The loop also features a configurable digital loop filter, a digital locking monitor, and a digitally controlled oscillator (DCO) for generating the feedback signal based on the detection signal.
