Abstract
A pulse generating unit including a delay unit for delaying an input signal of the pulse generating unit and a comparator unit for comparing an output signal of the delay unit with the above mentioned input signal, wherein the delay unit comprises one inverter for inverting the above mentioned input signal and for delaying the pulse fall time of the pulse fall edge of the inverted input signal, whereby the pulse generator generates an output pulse signal with a constant pulse duration even in the case where the pulse duration of the input pulse signal is shorter than the delay time of the delay unit.
