Abstract
A time measurement circuit (100) measures a time interval between two events. The time measurement circuit (100) includes two digital phase counters (10' and 10'), a period counter (210), and a digital calculator (310). The first digital phase counter (10') converts a time interval from a leading edge of a start signal to a leading edge of clock signal following the start signal into a first binary number. The second digital phase counter (10') converts a time interval from a leading edge of a stop signal to a leading edge of clock signal following the stop signal into a second binary number. The period counter (210) converts a time interval between the two leading edges of the clock signal into a third binary number. The digital calculator (310) combines the three binary numbers to generate a number representing the time interval between the start signal and the stop signal.
