electronics that can mechanically flex, span large areas, and integrate with polymeric materials. Potential applications include flexible displays, biochemical sensors, and artificial skin. In many applications, OTFTs act as an interface between the physical environment and the digital processors. Yet, a conspicuous absence in the field of organic electronics has been the lack of data converters. Because of the large process variations in OTFT fabrication – often orders of magnitude higher than those in silicon processes [1] – analog OTFT circuits have only been sparsely reported [2-3]. In particular, analog-to-digital converters (ADCs), which rely on component matching for accuracy, have not been demonstrated in an OTFT process thus far. We aim to address such deficiency with the design of this
