Hello,

I have schematic as follows: OpAmp_NF_estimation.TSC

Is it correct way to estimate NF of the diff-to-single Op-Amp circuit?

Thank you!

Tsa,
I will move your post to the High Speed Amplifier Forum.
The product experts that monitor that forum would be better able to help with your question.

Hi Tsa,

Taking the difference between the input SNR and the output SNR is one way of estimating Noise Figure of the Diff-to-single op-amp circuit.
