Inverting amplifier
A=(-Rf/Ri).
Non-Inverting amplifier
A = (1 + Rf/Ri).
A=(-Rf/Ri).
Non-Inverting amplifier
A = (1 + Rf/Ri).

It is an inverting amplifier.
A = (1+Rf/Ri).
BW = GBP/A.
BW = 50*200,000/[1+(1.2M/10K)].
BW = APPROXIMATE = 83.33Khz.
A = (1+Rf/Ri).
BW = GBP/A.
BW = 50*200,000/[1+(1.2M/10K)].
BW = APPROXIMATE = 83.33Khz.

Gain bandwidth product (GBP) =gain*corresponding frequency.
And bandwidth= GBP/gain.
So GBP=50*200000.
And.
As it is a non inverting amplifier it's gain= (-Rf/R1).
That is equal to -120.
So bandwidth = (GBP/gain).
83333 Hz.
And bandwidth= GBP/gain.
So GBP=50*200000.
And.
As it is a non inverting amplifier it's gain= (-Rf/R1).
That is equal to -120.
So bandwidth = (GBP/gain).
83333 Hz.

The bandwidth increases by (1+ab) times where a = open loop gain and b = feedback factor.
