I know I can use an op amp comparator, but perhaps there is an easier way with a capacitor or other method? I would like the input to be a square or sawtooth wave centered about zero, about 10vPP and the output to be a very narrow positive-going pulse (say ~5% Duty) of the same frequency. I've found some cap/transistor circuits that do what I want but provide a negative-going pulse that rests at high V+, but I want the inverse.
Any help would be appreciated!
