In this paper we present a novel front-end for resistive sensors based on a simple resistive voltage divider. This front-end utilizes a sampling technique to mimic the Wheatstone bridge in functionality, offers high precision and is fast at the same time more power conservative compared to the traditional Wheatstone bridge.
