Transcribed: a)
An operational amplifier has to be designed for an on-chip audio band
pass IGMF filter. Explain using appropriate mathematical derivations what
the impact of reducing the input impedance (Zin), and reducing the open
loop gain (A) of the opamp will have for the general opamps performance.
What effect would any changes to (Zin) or (A) have on the design of an
IGMF band pass filter?
