The file give and explanation about analog to digital converter input noise. All analog-to-digital converters (ADCs) have a certain amount of

input-referred noise—modeled as a noise source connected in series

with the input of a noise-free ADC. Input-referred noise is not

to be confused with quantization noise, which is only of interest

when an ADC is processing time-varying signals. In most cases,

less input noise is better however, there are some instances where

input noise can actually be helpful in achieving higher resolution.

If this doesn’t seem to make sense right now, read on to find out

how some noise can be good noise-The file give and explanation about analog to digital converter input noise. All analog-to-digital converters (ADCs) have a certain amount of
