Abstract: A circuit for the measurement of time intervals includes a generator providing primary periodic pulses, a frequency divider capable of transmitting secondary periodic pulses for scaling down the frequency of the primary periodic pulses, and a counter for counting the secondary periodic pulses transmitted during the measured time interval. The frequency divider is programmable by a digital factor which determines the frequency division. The circuit further includes a self-calibration circuit for modifying the digital factor as a function of the number of pulses counted by the counter during a previous time interval measurement.
