Q (100p):For the given circuit, V+ = 15 V, V− = −15 V, I1 = I2 = 0, 5 mA. R1 = R2 = 2 MΩ where R1 is the internal resistance of l1 current source and R2 is the internal resistance of I2 current source. Current gain of Q3 transistor is β = 80. VBE = 0.7 V, VA = 75 V and VT = 25 mV. M1 and M2 are identical MOSFETs where KP = μpCox(W/L) = 5 mA/V2 and VTP = −1 V. Considering DC conditions, VODC = 0 V. a) Calculate RD and the operating points of M1, M2 and Q3 transistors considering λ = 0 and ignoring base current of Q3 transistor. (30p) b) Draw mid-frequency small signal equivalent circuit. (You should add output resistance of Q3 to equivalent circuit.) (30p) c) Derive the expression of voltage gain v0/(v1 − v2) and calculate its value. (You should include the value of output resistance of Q3 in your calculations.) (40p)
