Figure 1 shows the cascade current source. If VT = 0.7 V and KP = 50 μA/V2, calculate: i. Current across M2, lM2 ii. Current across M3, IM3 Figure 1 2. Cascode current sink is as shown in Figure 2. If λ = 0.4 V−1, VT = 0.7 V, K = 110 μA/V2 and (W/L)1 = (W/L)2 = 1, calculate rout of the circuit. Figure 2
