Organic CMOS line drivers on foil
article
In this paper, the design of a low-voltage line driverin a complementary organic technology on foil is presented. Thebehavior and the variability of circuits are predicted by means oftransistor modeling and statistical characterization. The compar-ison of measurements and simulations of simple digital blocks ver-ifies the effectiveness of the design approach. A transmission-gatebased 32-stage line driver and a fully-static one are shown. It isalso shown that, based on the statistical organic thin-film transistor(OTFT) characterization, the fully-static logic style is a more suit-able choice for implementing line drivers in this technology. Theimplemented fully-static line driver, which is comprised of 1216transistors, has the highest transistor count reported for a comple-mentary organic circuit to date.It works at supply voltages from10Vtoaslowas3.3V,reachinga1kHzclockfrequency,andoc-cupyinganarea of 254.7 mm. The drivers are implemented ina technology compatible with that of flat-panel display backplanesand are tested with a QQVGA AMOLED display.
