摘要：

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