(a) Find the operating point of the pMOSFET of Fig. P6.8 if k9 5 50 A/V2 , W 5 10 m, L 5 1 m, Vt0 5 20.5 V, 5 0.445 V1y2 , 2n 5 0.6 V, and 5 0.05 V21 . Hint: assume 5 0 for dc analysis, and use iterations.

(b) Find the element values in the small-signal model of the MOSFET and show the fi nal circuit, given that Cox 5 3.6 fF/m2 , Lov 5 55 nm, Csb0 5 Cdb0 5 25 fF, Cgb 5 5 fF, 0 5 0.6 V, and m 5 0.5. (c) Estimate fT.
