hello every one, i have question regarding noise of an cascade stages. Let us say you have two stages, so to find the noise generally find the total TF of the system and multiply the spectral density and find the integral. This is very common and every one do this. But think about an opamp, at the input assume you have small gate resistance and gate capacitance (which is very small of course), so integrated noise at the opamp input very high (KT/C, due to small cap). any thing wrong in this?
Thanks, Raj.
