The FET in the current buffer of has k 5 2.5 mA/V2 , x 5 0.1, Cgs 1 Csb 5 1 pF, and Cgd 1 Cdb 5 100 fF, and is biased at ID 5 1.25 mA. (a) Sketch and label the frequency plot of uZi (jf)u assuming 5 0. (b) Sketch and label the frequency plot of uZo(jf)u if 5 1y(20 V). (c) Sketch and label the frequency plots of the current gain ua(jf)u for the cases RL 5 0 and RL 5 1.0 kV, compare and comment.
