For the circuit in Fig. E5.10, assume that Q1 and Q2 are matched except for having different widths, W1 and W2. Let Vt = 0.5 V, k’n = 0.4 mA/V2, L1 = L2 = 0.36 μm, W1 = 1.44 μm, and λ = 0. (a) Find the value of R required to establish a current of 50 μA in Q1. (b) Find W2 andR2 so thatQ2 operates at the edge of saturation with a current of 0.5 mA Figure E5.10
