Vss (b) Find ( Drav amp the variation of D 7.103 Figure P7.103 feedback-bias circuit of Fig. 7.50. Using a 5-V supply with an NMOS transistor for which V, =0.8 V, k. = 8 mA/V =0, provide a design that biases the transistor at I = 1 nA, with Vps large enough to allow saturation operation for a 2-V negative signal swing at the drain. Use 22 MS2 as the largest resistor in the feedback-bias network. What values of R R and R have you chosen?
