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. (a) Determine the quiescent voltages and currents of M1 and M2 when v1 = v2 = 0. (4 marks) (b) Design the value of resistor RE such that IQ = 0.1 mA. (2 marks) (c) Determine the maximum and minimum common-mode voltages that can be applied to v1 and v2. (3 marks) (d) Determine the percentage change in IQ when the common-mode voltage applied to v1 and v2 changes from the maximum to the minimum value obtained in part (c). (5 marks) (c) Define vd = v1 - v2, determine the differential-mode voltage gain Ad of the improved differential amplifier.

For the circuit shown in Figure 2, the MOSFET parameters are K = 0.25 mA/V2 and Vto = 1.4 V. (a) Assume the MOSFET is in the saturation region, calculate RD, Rs and VGS where IDQ and VD are given as 0.5 mA and 1 V respectively. (7 marks) (b) Check the assumption, is your assumption correct? You need to provide all calculation steps. (3 marks) (c) Plot output characteristic curve, draw the load-line and plot Q-point. (3 marks) (d) Choose standard resistor values that are closest to the ideal designed values for Rs and RD and calculate VDS, VGS and ID at Q-point. (8 marks) (e) If the standard resistor Rs has ±10% tolerances, determine the maximum and minimum values of IDQ. (4 marks) Figure 2
