The circuit of Figure P15.5 may be used for operation of a photodiode. The voltage VD is a reverse-bias voltage large enough to make the diode current iD proportional to the incident light intensity H. Under this condition, iD/H = 0.5 ?A-m2/W.
a. Show that the output voltage vo varies linearly with H.
b. If H = 1,500 W/m2, VD = 7.5 V, and an output voltage of 1 V is desired, determine an appropriate value for Ro.
