Homework Statement
Select component values to design for corner frequencies at 500 rad/s and 1500 rad/s.
Homework Equations
KCL, transfer function
The Attempt at a Solution
Gain:
[1] G = 1 + [itex]\frac{R_{A}}{R_{B}}[/itex]
Voltage division:
[2] V2 = V1[itex]\frac{R_{2}}{R_{2}+1/sC_{2}}[/itex]
KCL:
[3] 0 = [itex]\frac{V_{1}-V_{i}}{R_{1}}[/itex] + [itex]\frac{V_{1}-V_{2}}{1/sC_{2}}[/itex] + [itex]\frac{V_{1}-V_{o}}{R_{3}}[/itex]
I am stuck at this point and don't know what to do next. There is a similar problem in the book and it said to substitute equations [1] and [2] into [3].
I sort of know what to do once I find [itex]\frac{V_{o}}{V_{i}}[/itex], but I just don't know how to get there from where I am.
Thanks!
