Ultralow Power Transistors for Flexible Electronics
Prof. Arokia Nathan, FIEEE, FIET, CEng

Abstract - Oxide semiconductors have become an attractive material technology platform for thin film transistors in active-matrix arrays and sensor interfaces in view of their wide bandgap, hence high transparency and low OFF-current. While the thin film transistor continues to evolve, producing devices with higher mobility, steeper sub-threshold slope and lower threshold voltage, practical signal processing circuits are constrained by issues related to non-uniformity, electrically- and illumination-induced instability, and temperature dependence. In this presentation, we will discuss the critical design considerations of displays, sensors and sensor interfaces, along with advanced signal processing architectures to show how device-circuit interactions should be handled and how compensation methods can be implemented

Arokia Nathan is a leading pioneer in the development and application of thin film transistor technologies to flexible electronics, display and sensor systems. Following his PhD in Electrical Engineering, University of Alberta, Canada in 1988, he joined LSI Logic USA and subsequently the Institute of Quantum Electronics, ETH Zurich, Switzerland, before joining the Electrical and Computer Engineering Department, University of Waterloo, Canada. In 2006, he joined the London Centre for Nanotechnology, University College London as the Sumitomo Chair of Nanotechnology. He moved to Cambridge University in 2011 as the Chair of Photonic Systems and Displays, and he is currently a Bye-Fellow and Tutor at Darwin College. He has over 600 publications including 4 books, and more that 110 patents and four spin-off companies. He is a Fellow of IEEE, a Distinguished Lecturer of the IEEE Electron Devices Society and Sensor Council, a Chartered Engineer (UK), Fellow of the Institution of Engineering and Technology (UK), and winner of the 2020 IEEE EDS JJ Ebers Award.
