LTSpice - Digital - Pulse Generator on Edge? (monostable)

[ACharnley]

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).

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.

So take the out_clk, every time there's a falling edge create a small pulse (say 10ns)

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:

Brill will try that in an hour. Currently doing it as the attached. Works fine but want to keep to digital representation.
