K.U. Leuven, Leuven, Belgium Polymer Vision, Eindhoven, Netherlands 3 IMEC, Heverlee, Belgium 2 Organic electronics is expected to find commercial applications in flexible displays, RFID tags and smart sensor systems, e.g. for food industry or biomedical applications. Key benefits of the technology are the direct production of transistors and circuits on flexible plastic foils, the possibility to directly integrate sensors, light sources, light detectors, a.o. with the same technology, and the low processing temperatures that warrant cost-efficient production. However, organic electronics technologies suffer from important drawbacks versus silicon based technologies, such as its intrinsically lower mobility, the large parameter variation and a very low intrinsic transistor gain (typically 5). Moreover as active components almost exclusively p-type transistors are available and as passive components only capacitors exist. In place of resistors, we are limited to only
