Abstract

See full text

A circuit includes a signal generator, a delay pulse generator and a time-to-current converter. The signal generator is configured to generate a first signal including information on a rise delay and a second signal including information on a fall delay. A delay difference exists between the rise delay and the fall delay. The delay pulse generator is configured to provide an additional delay to one of the first and second signals. The time-to-current converter is configured to extract the delay difference.
