Abstract
A delay unit for providing an output signal delayed by a delay time with respect to a periodic signal received at its input, the delay unit comprises a first delay cell adapted to receive the periodic signal and to provide as output a first delayed signal corresponding to the input periodic signal but delayed by a variable first delay time. A selection unit receives the first delayed signal and a second signal derived from the periodic signal. A control unit controls the selection unit in order to select one of the first delayed signal and the second signal as the output signal of the delay unit, and further controls the first delay time of the first delay cell.
