Question 2.
Consider the common-source amplifier below having as active load the current mirror in question 1. Use the parameters: $W_3 = 6450$ nm, $L_3 = 120$ nm, $|V_{tp}| = 0.35$ V, $\mu_p C_{ox} = 200$ $\mu$A/V$^2$, $\lambda_p L = 0.05$ $\mu$m/V.
(a) Find the appropriate bias input voltage $V_{IN}$ for the output voltage to be at 0.5 V when the channel-length modulation is ignored.
(b) Calculate the bias input voltage $V_{IN}$ for the output voltage to be at 0.5 V when the channel-length modulation is considered.
(c) Determine the small-signal voltage gain $A_v = \frac{v_{out}}{v_{in}}$.
