S. MOSFET Multiple-stage Circuit with Feedback (25) In the following circuit, the MOSFETs have the following parameters: IVonk - 0.2 V, 1V) = 05 V, and V = 10 V.N.C. - 200 A/V...Cu = 100 A/V2A DC source of 1 -0.1 mA is used to bias 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 Qu.i.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.... V.. Vs as labeled 3) (10) With R. connected, draw the A-circuit and B-circuit Calculate the closed-loop gain Ay and output resistance R., based on the A- and B-circuit.
