Analog to digital converters on plastic foils

Circuits based on transistors which are manufactured at near-to-ambient temperatures on plastic foils are suited for mechanically flexible and large-area applications. Examples include bendable displays, large-area sensor surfaces for man-machine interfaces, and sensors-augmented RFIDs embedded in packaging material for food monitoring. This paper discusses circuit and system-level techniques that, minimizing the impact of the poor matching of organic transistors, enable analog to digital converters manufactured using unipolar and complementary organic technologies.
