Abstract

TFT-based sensors and senor interfaces have become a viable technical presence in large area electronics. They interact with environment and/or humans for data acquisition and signal pre-processing prior to CMOS-based peripheral electronics. “Active” sensors differ from “passive” sensors in that their signal-to-noise ratio can be improved by integrating TFT-based pre-amplifiers. This talk starts with an introduction on technical requirements and challenges faced in some exemplary applications including large area imagers, tactile sensors and wearable sensors, and followed by an overview on TFT-based circuit designs to enable efficient sensor interfaces along with a discussion on TFT-centric circuit design methodology.
