6. Refer to Figure Q6. The diode is biased with a constant current source 1 = 2.6 mA. A sinusoidal signal vs is coupled through the resistor Rs and the capacitor C. Assume that the capacitor C is large so that it acts as a short circuit to the ac signal. (a) Determine the quiescent diode current Ipo. (5 marks) (b) Determine the small-signal diode diffusion resistance rd. (3 marks) (c) Determine the small-signal gain vo/vs if Rs=290 22. (5 marks) V+ 1 Rs C WH ip | KH vo Figure 26
