Adding a Delay Ltspice

Question

Is it possible to set a delay between two components on Ltspice ? Actually I just want to simulate the time for a sensor it takes to react (set an output) to an exciting signal.

This is for taking into account the impact of a delay with respect to the stability of the system into an AC simulation.

Have a nice day !

This sounds exciting, ;) what frequency is the delay supposed to occur or Q which determines BW or is it an “all pass” delay? — Tony Stewart EE75, Jan 19 '21 at 16:26

Yes. You'd use the delay line element for that, or you can use a behavioral voltage source BV and use the behavioral delay function in it, for example:

SYMBOL bv 128 128 R0
SYMATTR InstName DLY1
SYMATTR Value V=delay(V(x),100n)

This element introduces a 100ns delay.

See this thread for discussion of various ways of adding delays in LTspice in general.

I'm a bit partial to using a lossless transmission line to accomplish this, but the `delay()` function in a B-source is probably much easier to implement. – Ste Kulov Jan 19 '21 at 22:11
