a) A MOSFET current source shown in Figure 2 has the following parameters: VTP = −0.4 V, kP′ = 60 μA/V2, (W/L)1 = 25, (W/L)2 = 15, (W/L)3 = 5 Determine the value of resistor R such that transistor M2 is biased at the edge of saturation region (where VSD2 = VSD(SAT)). Figure 2 b) After a design review, a senior design engineer has suggested to increase the output resistance (Ro) by adding ONE additional transistor. Modify the current source in Figure 2 to meet this requirement. Name the circuit, sketch and clearly label all components.

Consider the current mirror circuit shown in Figure 4 on page 6 where an additional resistor R is connected between the gates of the MOSFETS and ground. Assume all transistors are in saturation and you can ignore Early effect. (a) Given that IREF = 250 µA, Kn’ for the MOSFET is 10 µA/V2, VTN = 1 V, (W/L)1 = 5, (W/L)2 = 10 and R = 20 kΩ, find the values of the DC voltage VGS1 and DC currents ID1 and ID2. (10 Marks) (b) Perform an AC small-signal analysis to find an algebraic expression of the input resistance Rin in terms of the transconductance gm of the MOSFETS and the resistor R. Indicate clearly the gm of the i-th transistor as gmi. For example, the gm of transistor M1 should be written as gm1. (5 Marks) (c) Using the transistor parameters and resistor values given in part (a), find out the magnitude of the input resistance Rin found in part (b). (5 Marks)
