Hi,
in the related post, Art Kay gives the method of calculating R1 noise and Rf noise independently.
But I find that it doesn't count for BWn.
I wonder how to calculate BWn for R1 noise and Rf noise.
For example, I think Rf noise…

Hi,
In TI Precision Lab Training about OP AMP noise part3,
voltage noise is divided into 1/f noise and broadband noise.
1/f noise is calculated with a complex equation.
Can we use the parameter offered in the datasheet "input voltage…
Hi Nasifa,
This approach will not work for your EXT node because you are removing the feedback component of the loop. The output is modified by itself through feedback so by removing the feedback you are fundamentally changing the output signal.
This…
