Patent ID: 7205814

Claim:
A pulse generator comprising: a first driving unit having first and second inputs, an output and being turned on and off by a first input signal to said first input to said first driving unit and by a second signal input to said second input; a latch having an input and an output, said latch input being coupled to the first driving unit output and which latches first power supply voltage from the first driving unit; a delay circuit having an input coupled to the latch output and an output coupled directly to said second input of first driving unit, said delay circuit receiving a positive-going signal at its input and delaying the output of said positive-going signal to said second input of said first driving unit by a predetermined time; and a second driving unit having an input directly coupled directly to the delay circuit output and having an output coupled to the input of the latch and being turned on and off by an output signal of the delay circuit; wherein the latch holds a second power supply voltage when the second driving unit is turned on and a pulse width of the output signal of the latch is determined by said delay circuit regardless of a frequency of the input signal.
