2. The values of the circuit elements in Figure 2 are as follows: VDD = (5000+a) mV, Rs = (10000+ẞ) Q, RD = (5000+y) Q, RG1 = (30+5) KQ, RG2 = (20+) kQ, C= 10 μF. Vin 100 sin (20000πt) mV. The MOSFET parameters are: V = (500+2) mV, μnCox = 200 μV/A2, (W/L) = 4 μm/1 μm, An = 0.01 V-1. (i) (ii) (iii) Calculate the DC and small-signal components of Vout. (20 points) Use LTSpice to plot Vout as a function time. (10 points) If the result of (ii) is different from (i), explain why. (5 points) VDD Vin Ο RG1 RG2 Figure 2 www RD M1 Σ www Rs www www Vout
