In this amplifier circuit, the high and low DC voltage sources are: VDD = 5 V and VSS = −5 V respectively. Consider that all three external capacitors have high values. The PMOS transistor has a threshold voltage equal to Vt = −1 V and kp = kp′(W/L) = 0.4 mA/V2, and the NMOS transistor has a threshold voltage Vt = 1 V and a kn = kn′(W/L) = 2 mA/V2. It was shown in HW#7 that the DC drain voltage of the PMOS transistor is −0.2 V and the DC source of the NMOS transistor is −2 V. a) Perform the small signal analysis of this circuit and determine the voltage gain: AV = Vo/Vi b) Determine the input and output resistance of this amplifier Rin and Rout . c) Discuss what is the purpose of the part of the circuit between CC2 and CC3 which includes the NMOS transistor in this amplifier design. d) Determine the parameters of a simple voltage amplifier model (discussed in chapter 1) which will represent this amplifier. Note that the parameters of the simple voltage amplifier excludes any series resistance of the external source ( Vi ) (in this case it is zero anyway) and the load resistance (in this case RL = 2 kΩ ). e) Using the simple model from part (c) determine the voltage gain AV = Vo/Vi and see if it agrees with the answer of part (a).

QUESTION 3 This question examines large signal behaviour of transistor circuits (a) Assume that the MOSFET in Figure 3.1 is operating in saturation and is characterised by a threshold voltage, VT = 1 V. Assume that the parameter, K = 1 mA/V2 where the drain-source current in the MOSFET in saturation is given by equation (3.1). iDS(sat) = K2(vGS−VT)2 Show that the gate-source voltage, vGS, for the circuit shown in Figure 3.1 may be written in terms of the input voltage, vIN, and the output voltage vO, by equation ( 3.2 ): vGS = vINR2 R1+R2 + vOR1 R1+R2 Figure 3.1 (b) For the circuit shown in Figure 3.1, calculate the minimum possible value of output voltage, vO when vIN = 5 V assuming that the MOSFET is maintained in saturation. Assume Rl = R2 = 10 kΩ, and RL = 1 kΩ (c) For the circuit shown in Figure 3.1, determine the value of the constant voltage source, VS, if vO = 4 V when vIN = 5 V and all other circuit parameters are as descirbed in Q3, part (b).
