(a) Assuming Cgb, Cgd, Csb are negligible compared to Cgs in the source follower of Fig. P6.27, fi nd Rx, Lx, and Ry if RG 5 5 kV and IBIAS 5 1 mA, and the FET has k 5 2 mA/V2 , 5 0.05 V21 , 5 0.125,...

(a) Assuming Cgb, Cgd, Csb are negligible compared to Cgs in the source follower of Fig. P6.27, fi nd Rx, Lx, and Ry if RG 5 5 kV and IBIAS 5 1 mA, and the FET has k 5 2 mA/V2 , 5 0.05 V21 , 5 0.125, and Cgs 5 1 pF. (b) Sketch and label the frequency plot of uZo(jf)u from 1 MHz to 100 GHz (use logarithmic scales). (c) Use physical insight to discuss how the plot is affected if Cgb 5 Cgd 5 50 fF and Csb 5 100 fF. Hint: fi nd Zo`.
