An apparatus for generating a monostable signal is disclosed. The apparatus comprises a flip-flop, an oscillation circuit, a counter and a comparison circuit. The flip-flop, in response to a trigger signal, activates a first edge transition of the monostable signal at an output terminal. The oscillation circuit generates a pulse train, responsive to the first edge transition. The counter counts number of pulses of the pulse train. The comparison circuit, comparing the output of the counter with a predetermined value, generates a clear signal to said flip-flop in order to activate a second edge transition of the monostable signal. The desired pulse width of the output signal is controlled by the predetermined value.
