To improve the performance of the differential amplifier shown in Figure Q1, the biasing current source is replaced by a Widlar current source. The collector resistors are replaced by a current mirror formed by the matched bipolar transistors Qs and Q6, and the bipolar transistors Q1 and Q2 are replaced by the matched field-effect transistors M1 and M2. A single-sided output at the drain terminal of M2 is used. The transistor parameters for the bipolar transistors are: β = 100, VBE (on) = VEB(on) = 0.7 V, and VA = 100 V. The transistor parameters for M1 and M2 are: Kn = 0.15 mA/V2, VT N = 0.8 V, λ = 0.01 V-1 . The improved differential amplifier is shown in Figure Q2.

For the amplifier below, following design information is provided: VDD = 3.3 V, R = 2.4 kΩ, ISS = 1.8 mA, k1 = k2 = 5 mA/V2, VTH,1 = VTH,2 = 0.5 V, λ = 0.1 V−1, γ = 0, ki′ = μ0Cox, ki = μ0 Cox(W L)i. Assume that both transistors are identical and in the saturation region. Finally, NMOS and PMOS bulk terminals are connected to the ground and VDD, respectively. a) What is the DC bias voltage for M1 and M2 given that the voltage drop across ISS is 0.4 V ? You can neglect the channel length modulation, here. Check that the transistors are in the correct operation-mode. b) The resistors will be realized using identical PMOS transistors M3 and M4. If the transistors to be used will have k3 = k4 = 1.5 mA/V2, what will be their overdrive voltages? Check that the transistors are in the correct operation-mode. c) What is the differential voltage gain AV,diff = Vout/Vid in dB ? d) ISS will be realized as a cascode current source. Assume that the voltage drop of 0.4 V is equally shared by the two transistors, M5 and M6 having k5′ = k6′ = 0.5 mA/V2 and VTH, 5 = VTH, 6 = 0.5 V. Assuming the gate voltages of both transistors are 1 V, find the W/L ratios of each device. Once again, you can neglect the channel length modulation here. e) Considering (d), how would the W/L ratios qualitatively change (increase/decrease/stays the same), if γ > 0 ? Explain your reasoning analytically, i. e. , using appropriate equations. f) Using the cascode current source, calculate the common-mode gain of the circuit AV, CM = Vout /Vin in dB, where Vin . s applied to the gates of both M1 and M2.
