Abstract
This letter analyses the low-frequency noise reduction produced by the autozero technique. A very simple model is established, and the output average power spectrum in the case of lowpass filtered white noise and 1/f noise is calculated. This analysis clearly shows the limitation to low-frequency noise reduction introduced by the foldover effect.
