5. MOSFET Multiple-stage Circuit with Feedback (25) In the following circuit, the MOSFETs have the following parameters: "Vox = 0.2 V. 1V. - 05V, and Vil = 10 V..Cox = 200 HA/V2.Ca = 100 A/V2A DC source of 1 -0.1 mA is used to bins all three MOSFETs. The current source has an equivalent output resistance of 50 kn 1) (5) Show that the feedback is negative. 2) (10) For the open-circuit output (without R.) case, specify the W/L ratio of the MOSFETs Determine the DC voltages at the gate, drain and source of Qui.e. V. V; and V, as shown in the schematic. Also, assume there is no DC current flowing through R. calculate the DC voltages at the gate and source of Q... i.e., Va. Vs as labeled (10) With R. connected, draw the A-circuit and B-circuit. Calculate the closed-loop gain Ag and output resistance Rer based on the A- and B-circuit.
