A ACharnley Member Jan 31, 2022 #1 Is there an out-the-box digital control that'll do it? I can generate using components but want to keep it clean with a single digital control if possible (better replication of the MCU which will be doing it in software).

danadak Well-Known Member Most Helpful Member Jan 31, 2022 #2 Is this what you are trying to do ? The above also allows you to control the pulse width generated at output. Or is this - What is the rate at the input, latency to output, and output pulse width range you want ? Regards, Dana.

E eTech Well-Known Member Jan 31, 2022 #4 Hi There is no pre-made leading edge detector in LTspice. but you can make one like this: The two schmitt buffer devices provide input hysteresis for the AND device The inverter "delay" device sets the pulse width using the Td parameter. A trailing edge detector:
