Hello
I'm a bit unsure on how to calculate the input-refered noise for two OTA in parallel.
Lets say that both OTA have a input referred noise level of Vn = 60 nV/sqrt(Hz) individually.
I have read that if I regard two noise sources connected in series as uncorrelated i can add them.
If i connect the two OTAs in parallel and refer the noise to the input, will the noise become bigger or smaller?
