Q1. Consider the circuit shown in Figure 1, where (W/L)1 Assume Cox saturation mode.) (Note 2: Vx=VDs2) a) Transistor are biased at 1mA drain current. What is the highest allowable value of 20/0.18 and (W/L)2 = 40/0.18. 0.4V. (Note 1: Both M1 and M2 should be in VDD = 1.8V 100A/V? and VTH RD = 500 Q V. Vbl =. .V Vb1 M1 b) With such a value chosen for Vb1, what is the value of Vx. X Vx=. .V Vb2 M2 Figure 1 T
