Amplifying AC signals with large DC offsets for Low Power Designs

PDF

This KWIK (Know-how With Integrated Knowledge) Circuit application FAQ offers a step by step guide that will assist with the design of a low power, AC coupled signal conditioning circuit .

This design will both reject the large offset voltage and amplify the small differential signal. Additionally, this guide will help with partitioning of the gain stages around the high pass filter as well as any noise considerations.
