For the given circuit assume the following circuit parameters:

$g_{m} = 40 m S$
$B = 100 A / A$
$r_{0} = \infty$
$C_{π} = 18 p F$
$C_{μ} = 2 p F$

Assuming:

$R_{I} = 75 Ω$
$R_{E} = 5 k Ω$
$R_{C} = 3 k Ω$
$R_{3} = 50 k Ω$

Find the mid-band voltage gain $A_{mid}$ .
Determine all zero and pole locations a low frequencies.
Estimate the lower frequency corner $w_{L}$ .
Redesign the value of $C_{1}$ required to set $f_{L} ($ new $) = 400 H z$ .
Determine all pole locations a high frequencies.
Estimate the lower frequency corner $w_{H}$ . $A_{mid} =$ $◻$ $V / V$

Low Frequencies

$z_{1} =$ $◻$ $r a d / s$
$Z_{2} =$ $◻$ $r a d / s$
