Record performance of dual-gate organic TFT-based RFID circuit

09.02.2010
At today’s International Solid State Circuit Conference (ISSCC), Holst Centre, imec and TNO present a dual-gate-based organic RFID chip with record data rate and lowest reported operating voltage. For the first time, the advantages of dual gate transistors in circuit speed and robustness have thereby been exploited in a complex organic-electronic circuit.

Organic RFID tags are one of the drivers of flexible electronics research and development. Over the previous years, Holst Centre, imec and TNO, have been successful in reporting state-of-the art results on major conferences, such as ISSCC and IEDM. The current result of a 64-bit transponder circuit at 4.3kb/s shows an improvement of over a factor two compared to the result reported last year at ISSCC. What’s more, results show that chips start to operate at lower voltages (down to 10V), making them more suitable for capacitive and inductive coupling with a readout station.

Main reason behind the increased performance is the use of a dual gate unipolar transistor technology, adapted from rollable-display company Polymer Vision, one of the partners in the Holst Centre research programs. Using a dual gate allows controlling the threshold voltage (Vt) and the thus obtained multiple-Vt technology leads to more robust circuits.

Dual-gate organic TFT (thin-film transistor) circuits have been reported before, but had never surpassed the complexity of basic inverters. Thanks to the tight collaboration within mixed teams of circuit designers and technology developers, Holst Centre, imec and TNO now report 99-stage dual-gate ring oscillators in various topologies, plus 64-bit RFID transponder chips using the same architecture.

Further and ongoing work will demonstrate the viability of the technology towards industrial uptake. Holst Centre therefore gathers leading industrial players from across the value chain around its shared research roadmaps. The work is the result of a close collaboration between TNO and imec teams in Eindhoven and Leuven.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
