Let M1 and M2 in Fig. P4.19 be matched devices with k 5 200 A/V2 , Vt 5 1.0 V, and 5 1y(50 V). Moreover, let M3 have k9 5 30 A/V2 , Vt 5 21.0 V, and 5 1y(30 V). (a) Specify the ratio W3yL3 so as to bias the output node at VO 5 0 V. (b) Find Ro and voyvi . (c) Estimate vO(min) and vO(max), the lower and upper limits of the linear region of operation.
