Abstract

See full text

A multi-chain measurement circuit is disclosed. The measurement circuit includes first and second chains of serially-connected buffer circuits coupled in parallel, each of which propagates an input signal. A set of storage circuits is configured to store logic values generated by the first and second sets of buffer circuits in response to the transitioning of a clock signal. The logic values stored in the storage circuits result in a digital value indicative of a total number of serially-connected storage circuits through which the input signal has propagated at the time of the transition of the operating clock signal.
