A pn diode is fabricated by adding a concentration of donor atoms,ND = 4.25 x 10^17 cm–3 into the surface region of a p-type silicon waferwith an acceptor concentration of NA = 1.05 x 10^15 cm–3. Calculate thedepletion capacitance with zero applied bias across the device.
A silicon diode is forward biased at 0.9V. Find the resulting diode current. Note: T = 25C, IS = 1pA, n = 1
Given a diode current of 8 mA and n 1, find I s if the applied voltage is 0.5 V and the tem-perature is room temperature (25°C).
