For the MOSFET current source of Fig. Q1(b), the circuit values are VDD = +12 Volts, VSS = 0, and IREF = 100 μA. The transistors are matched and their parameters are VT = 1.8 Volts, kn = 250 μA/V2 and λ = 0.01 V−1. Calculate ILOAD for (i) VDS2 = 2.5 Volts, (ii) VDS2 = 4 Volts and (iii) VDS2 = 10 Volts. Calculate the value of for which transistor T2 enters the linear region and hence determine the range of RLOAD values that can be used for this current source. Fig. Q1(b)

(b) For a MOSFET current source shown in Figure 3, the bias voltages are V+ = 1.5 V and V− = −1.5 V. Transistors are available with the parameters: kn' = 200 μA/V2, VTN = 0.5 V, and λ = 0. Figure 3 (i) Design the circuit such that IREF = 100 μA, IO = 250 μA, and VDS2(sat) = 1 V. [10 Marks] (ii) Calculate the change in output current, dIo and hence the output current Io when VDS2 = 3 V.

(a) Figure Q2(a) shows a differential amplifier with a current source at the bottom. It is given that VDD = VSS = 15 V, ISS = 300 μA, Early effect can be ignored (λ = 0), Kn = 400 μA/V2 and VTN = 1 V. You may assume MOSFET in saturation region. (i) For single ended outputs, draw the half-circuits and derive the algebraic equations for the differential mode and common-mode gains as well as CMRR. [6 Marks] (ii) For the above case of single ended output, what should be the value of Rss to get CMRR = 100? [4 Marks] Figure Q2(a) (b) Figure Q2(b) shows a MOSFET based current mirror. Draw the AC small signal model and derive an equation for output resistance Rout as shown in the figure. You can keep your answer in terms of gm, ro etc but denote the subscript 1,2,3 etc to indicate which transistor. In other words, denote transconductance of M2 by writing gm2 and so on. [6 marks] (c) Draw the diagram of a BJT based Class B push-pull power amplifier and derive the maximum possible power efficiency of this circuit. You may ignore crossover distortion and assume |VCE(sat)| = 0 V. [9 marks]
