Q5 Figure 5 shows the circuit diagram for a two-stage amplifier. You may assume that the parameter is ß= 0.02 A/V², V: = 0.4 V, and VA = 10 V for each transistor. All other values are shown beside the schematic. (a) What kind of configuration is used for the 2 stages amplifier? (b) What kind of amplifier is M1 part of ? and what about M2? In which region should both transistors operate for a better voltage amplification gain? Calculate the corresponding DC Ins for Mi and M2. (c) (d) Calculate gm and ro for M1 and M2. Draw the combined small-signal equivalent circuit suitable for mid band frequency range analysis. There is no capacitor in parallel with Rs2. State any assumption. (e) (f) Determine the numerical values for: (i) Voltage gain of the entire amplifier. (ii) Output resistance of the entire amplifier. Vpp VDp = 2V R, Rp1 Rp2 R = 4KQ M2 HE Pout R, = 4KQ M1 Cp2 RpI = 4KQ Vin H Rp2 = 4KQ Rs = 4KQ R, Rsi Rs2 Rs2 = 6KQ Vss = 0 V Figure 5
