Hi All,

I was wondering if some of you guys happen to know a simple circuit to
create a 1us (approx.) delay for a 20kHz PWM signal coming out of a
PIC. I need this to create a death-time in order to avoid current
shoot through in an H-bridge.

The circuit I have right now consists of a small RC to slow down the
ramps of the pulse, followed by a comparator with significant
hysteresis. The comparator hysteresis is set at 1/3 and 2/3 of vdd.
This circuit seems to work ok, but I was wondering if there were other
options too. Or is my current approach not so bad after all?

Thanks!

Daniel...
