Hello,
I'm having a little difficult how to solve the circuit that I attached. The question is: Find the bias points, Vd and Id, by using (i) an iterative approach, and (ii) assuming Vd is .7 V.
I'm given: Is = 10^-15, n = 1, thermal voltage (Vt) = 25 mV
I know the equation Id = Is(e^(Vd/(n*Vt))
However, for part (i), I don't know how i can find Vd of the diode, since I would have assumed it was 0, since it would be like a short. If you plug 0 into the equation, you get 10^-15 amps, which I would not think makes sense, if it is acting like a short.
Also, for part (ii), I would just plug in .7 V to the equation? That seems a little too easy, since he asks the same two questions on another circuit which I have not posted.
Thanks for any help.
