For all the circuits below, use the constant-voltage-drop diode model (VD=0.7V), VT=25.9mV, and n=1.
a) Find VOUT, ID, and the small signal diode resistance, rd. (10 points)
Assume for the following circuit that the diode is forward biased and there is a small-signal AC signal, vi,AC, in series with a DC voltage.
b) Derive the small-signal AC transfer function vo,AC(s)/vi,AC(s). (10 points)
c) Assume that RS=1kΩ, C=1μF. Calculate the value of ID and VS necessary to set the magnitude of the pole frequency of the AC transfer function, |ωp|, equal to 10krad/s. (10 points)
