Consider the diode terminal I-V relationship stemming from the physics of the underlying pn junction: where I0 is the saturation current and VT = kT/q is the thermal voltage. a. Sketch the I-V characteristic for I0 = 10 fA and VT = 25.9 mV by plotting 10 points and drawing a smooth curve through them. b. Label the part of the characteristic that corresponds to: i. forward bias ii. reverse bias
