So I am newbie with LTspice and I need some help.
I am trying to simulate variable resistor, like photoresistor.
The key here is that the flux is changing with some law.
That law is a sine wave.
So we have a light source that changes it flux with the following law:
\( \Phi (t)=\Phi _0 (1+sin(\omega t+\phi ))\)
And the resistor value is determined by:
\( R=R_0 e^{-A\Phi } \)
I want to make such resistor in LTSpice, that is changing resistance in given law, with given flux. But I am unfamiliar with the functions in LTSpice and their parameters.
So I want to write function
\( R=R_0 e^{-A\Phi _0 (1+sin(\omega t+\phi )) } \)
And I want to see voltage across it in time. Say like 10 sec.(I will adjust the frequency of the sine later)
