WebDec 8, 2016 · Another important effect of input current is added noise. Luckily, noise is just a time-varying offset, so you can calculate the effect of noise just as you calculated the effect of offset. For example, the output-voltage noise due to the input-current noise is simply Another issue worth mentioning is internal input-bias cancellation.
