Abstract
A circuit for detecting and correcting timing errors. A timing circuit includes an interpolator. The interpolator includes a fine counter, a coarse counter, and stop correction logic. The coarse counter is incremented by a rollover output of the fine counter to generate a coarse count value. The stop correction logic is coupled to the fine counter and the coarse counter. The stop correction logic divides each cycle of the rollover output into first, second, and third time intervals, and selects a coarse counter output value to represent a time interval measured by the coarse counter based on a one of the first, second, and third intervals in which a time measurement stop signal is detected.
