Question	—	Correct way to think about thermal noise? I have just started learning about thermal noise in op-amps and while studying could not find if the noise given in op-amps data sheets is random sample to sample regardless of the time interval between the samples or if the randomness of noise is thought about in terms of unit time. If a data she... (more)	—	9 months ago
Comment	Post #289090	Is my understanding regarding 99.7% probability for noise correct? I interpret it as follows: 99.7% probability means that out of 1000 samples, noise will be out of the -Vpp/2 to Vpp/2 range for 3 samples. (more)	—	10 months ago
Comment	Post #289090	Thank you Lorenzo. It is a really great answer. I was not expecting the answer to be this complete/exhaustive. Is it possible I can connect with you via email or maybe you have your own website? (more)	—	10 months ago

Question	—	Is the noise of op-amps and ADCs Gaussian, possibly with zero mean? I understand that white noise is not always Gaussian. In general, is the $V{pp}$ and $V{RMS}$ noise stated in operational amplifier and ADC datasheets Gaussian? And is its mean zero? Any exemptions to be aware of while selecting an operational amplifier? My guess for interpreting the $V{pp}$ of n... (more)	—	10 months ago
