In this paper a fully integrated organic DC-DC up-converter is presented in a pentacene p-type only technology. This 3-stage Dickson converter reaches a voltage conversion factor of 3 for a purely capacitive load and 2.5 for a 10 μA load current. The maximal output voltage goes up to 75 V and the Dickson core efficiency is 48 %. The clock signal is generated on-chip with a 9-stage ring oscillator,...
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 f c =13.56MHz, a data rate of f c /512=52.969kb/s. In this work, we show that the compatibility of organic semiconductors...
Last year, advances in organic device technology (such as device scaling, high K-dielectrics enabled a substantial progress in performance. This resulted in an increase in the data rate of plastic transponder circuits from about 2 kbit/s to EPC-compatible speeds (50 kbit/s). The organic semiconductor pentacene deposited from solution was replaced by a better-performing vapor-phase deposited pentacene,...
We present our recent achievements in organic semiconductor technology in two emerging application areas. We show that the performance of our technology approaches the requirements for Electronic Product Coding RFID tags. Also, backplanes of OLED displays are enabled by the unique compatibility of pentacene transistors with high-k gate dielectrics.
In the present work, we demonstrate a plastic diode that can operate in the ultra-high frequency (UHF) band and rectify an incoming AC voltage at those frequencies.
RFID systems operating at a base carrier frequency of 13.56 MHz can use low-cost inductive antennas on foil. In parallel to this coil, a capacitor on foil is used for matching the resonance frequency at 13.56 MHz. This LC-antenna detects the signal transmitted by the reader and energizes the organic rectifier with an AC-voltage at 13.56 MHz. From this voltage the rectifier generates the DC supply...
