Abstract:
A pulse generator, comprising:a NOR gate having a first input, a second input, and an output; an inverter having an input connected to said output of said NOR gate and an output; an output terminal connected to said output of said inverter; an input terminal for receiving an input signal and connected directly, via a: first signal path, to said first input of said NOR gate; a delay element having an input connected to said input terminal and an output, said delay circuit receiving the input signal and delays propagation of the input signal by a delay time; and a buffer circuit having a first input connected, via a second signal path, to said input terminal, a second input connected to said output of said delay element, and an output connected to said second input of said NOR gate, said buffer circuit receiving and being set by the input signal virtually without delay, said buffer circuit being reset after an expiry of the delay time defined by said delay element and leads to a generation of an output pulse with a defined minimum pulse length available at said output terminal if the input signal is less than the delay time, and if the input signal is longer than the delay time, a pulse length of the output pulse is defined by a pulse length of the input signal.
