Hi, I am doing a Pre-Amp (An OPAMP with resistive feedback) that would drive an ADC. The SNR requirement for whole chain is > 80 dB.
Now my quetion is, Is the input referred noise at the OPAMP input or the noise output at the output of OPAMP (input to ADC) important?
If I take Input referred noise then, How would I simulate this in Spectre, what to choose for Input source (Is it main input to the OPAMP?)
Thanks in advance, Packiaraj V.
