Abstract

A method for providing a plurality of narrow pulses is provided. A first pulse having a first width is received by a delay line having a plurality of delay cells. This first pulse has a first width. In response to this first pulse, a plurality of second pulses is generated by the delay line, where each second pulse has a second width that is less than the first width. First and second delay pulses are also generated by the delay line, and a delay for each delay cell in the delay line can then be adjusted if a rising edge of the second delay pulse is misaligned with a falling edge of the first delay pulse.
