Is this equation in the photodiode model wrong?

If the paper's formula were true the Vout should have started from 4V. But it starts from 50mV. (?) Am ignoring the fact that OP's diode polarity is incorrect, and am assuming photocurrents produce +...

Is this equation in the photodiode model wrong?

Check the PULSE command in your simulation. The duration (width) of the current pulse is probably too short, only 0.2ns (ignoring rise and fall times). Did you mean 0.2us (microseconds rather than ...

Is this equation in the photodiode model wrong?

In this situation, the authors are assuming small values of current generated from the photodiode, so the voltage never gets big enough to turn on the diode. This would also be the case if the diode ...
