Question
(To solve this problem, you will FIRST need to use a model for the given diode.
Using the "accurate model" makes perfect sense here (draw the iv graph corresponding to the photodetector diode to see why).
An approximation for the contribution 1E-7 * (e38.5*V-1) to the overall current I when the diode is reverse biased is therefore -1E-7.)
a) In the circuit above, find the approximate value of the current (I), of the node voltage (Va), and of the diode voltage (V), under no light conditions.
b) In the circuit above, find the approximate value of the current (I), of the node voltage (Va), and of the diode voltage (V), under bright light conditions.
