In this paper, the design of a low-voltage line driver in a complementary organic technology on foil is presented.

It is also 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. The implemented fully-static line driver, which is comprised of 1216 transistors, has the highest transistor count reported for a comple- mentary organic circuit to date. It works at supply voltages from 10 V to as low as 3.3 V, reaching a 1 kHz clock frequency, and oc- cupying an area of 25  4.7 mm .

Abstract
In this paper, the design of a low-voltage line driver in a complementary organic technology on foil is presented. The behavior and the variability of circuits are predicted by means of transistor 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-gate based 32-stage line driver and a fully-static one are shown. It is also 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. The implemented fully-static line driver, which is comprised of 1216 transistors, has the highest transistor count reported for a comple- mentary organic circuit to date. It works at supply voltages from 10 V to as low as 3.3 V, reaching a 1 kHz clock frequency, and oc- cupying an area of 25  4.7 mm . The drivers are implemented in a technology compatible with that of flat-panel display backplanes and are tested with a QQVGA AMOLED display.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
