Organic transistor technology options for device performance versus technology options for increased circuit reliability and yield on foil

Last year, advances in organic device technology (such as device scaling, high K-dielectrics [1], ... ) enabled a substantial progress in performance. This resulted in an increase in the data rate of plastic transponder circuits from about 2 kbit/s [21 to EPC-compatible speeds (SO kbit/s). The organic semiconductor pentacene deposited from...

Organic RFID transponder chip with data rate compatible with electronic product coding

Data rates of plastic transponder chips have been limited to a few kHz, limited by the inherent low mobility of organic semiconductors. However, a target application for plastic RFID tags is Electronic Product Coding (EPC), which will require, at a base carrier frequency fc = 13.56 MHz, a data rate of fc/512 = 52.969 kb/s. In this work, we show...

Organic complementary oscillators with stage-delays below 1 μs

Recently, complex circuits of organic thin-film transistors have been shown. The use of complementary logic can significantly ease the design of large integrated circuits. However, the performance of complementary logic in organic thin-film technology has not been able to equivale that of unipolar logic, due to the difficulty to densely...

Robust digital design in organic electronics by dual-gate technology

Research towards organic RFID tags is one of the drivers of organic electronics. In recent years, 64b organic RFID tags have been shown with capacitive coupling [1] and inductive coupling at 13.56 MHz [2,3]. Recent improvements were a 128b organic transponder chip with basic anti-collision and Manchester encoding [4] and a first 4b tag in...

Towards EPC compatible plastic RFID tags

A target application for plastic RFID tags is Electronic Product Coding (EPC). The EPC-specifications set some demanding requirements for RFID tags.

We describe a complete 64-bit RFID tag that is inductively-coupled at a base carrier frequency of 13.56...

Controlled deposition of highly ordered soluble acene thin films: Effect of morphology and crystal orientation on transistor performance

(Figure Presented) Controlling the morphology of soluble small molecule organic semiconductors is crucial for the application of such materials in electronic devices. Using a simple dip-coating process we systematically vary the film drying speed to produce a range of morphologies, including oriented needle-like crystals. Structural...
