I'm on a bit of a roll with TIA designs at the moment, but I've just been using current sources with caps in parallel to model fully-depleted photodiodes, and I need a better model to hack up.
The LTSPICE Yahoo group's files area is broken at the moment. Do any of you have a decent PD model with 4 terminals (anode, cathode, and two to represent the light input)?
Nonlinear capacitance would be a plus but isn't required.
(I've used SPICE more in the last two weeks than in my entire previous career--I'm more of an algebra guy when it comes to circuit design, but some things really need sims.)
