Assuming $\backslash$lambda $>0$ and using Miller's theorem, determine the input and output poles of the

stages depicted in Fig. $11\mathrm{.}80.$

Figure $11\mathrm{.}80$

In the CS stage of Fig. $11\mathrm{.}29($a$),$ R$\_($S$)=200\backslash$Omega $,$R$\_($D$)=1$k$\backslash$Omega $,$I$\_($D$1)=1$mA$,$C$\_($GS$)=50$fF$,$

C$\_($GD$)=10$fF$,$C$\_($DB$)=15$fF$,$ and V$\_($GS$)-$V$\_($TH$)=200$mV$.$ Determine the poles of the circuit

using $($a$)$ Miller's approximation, and $($b$)$ the transfer function given by Eq$.(11\mathrm{.}70).$ Compare

the results.

Consider the amplifier shown in Fig. $11\mathrm{.}81,$ where V$\_($A$)=\backslash$infty $.$ Determine the poles of the cir$-$

cuit using $($a$)$ Miller's approximation, and $($b$)$ the transfer function expressed by Eq$.(11\mathrm{.}70).$

Compare the results.

Repeat Problem $40$ but use the dominant$-$pole approximation. How do the results compare?
