How to Use Zero-Drift Amplifiers in Wider Bandwidth Applications
This article provides a short description of chopping, auto-zeroing, and the sources of zero-drift artifacts, including a summary of some techniques that amplifier designers can use to reduce their impact. It also explains how to minimize the impact of these residual AC artifacts in a precision signal chain, including matching input source impedance, filtering, and frequency planning.
