Spice circuits with photoresistors or photodiodes

[Nicolae Fieraru]

Hi All,

I would like to simulate a circuit with a photoresistor or photodiode, to
see how it acts when it receives a light signal. What are the solutions that
can be used? I don't have such components in my component list. I am not too
concerned with characteristics of the photodiode/photoresistor, just the
response of the circuit.

Regards,
Nicolae

Model the current induced by the incoming light using a current source.
There are SPICE models of optocouplers on the net.

hi
im azeem from dubai my profession is techinician i need a circuit
diagram for uor own product of prolink we have vcd dvd cameras and lots
of more elctronics things so i need a circuit diagram for vcd player
dvd player the model no is prs 603 and prs 699 can give me this
diagram please

im in waiting

yours friend azeem
