Presentation Summary

  • Asynchronous-logic circuits are a class of digital-logic circuits that operates without a global clock. This class of circuits are traditionally used to address the challenges pertaining to silicon electronics operating at extreme process corners, e.g. sub-threshold supply voltages and large process, voltage and temperature variations.
  • Printed electronic circuits, due to its coarse manufacturing approach, are inherently more variation prone (at nominal process corners) compared to silicon electronics. Therefore, asynchronous-logic circuits can potentially improve the robustness of printed electronic circuits.
  • In this talk, fully printed asynchronous logic gates will be demonstrated on plastic films, followed by a robustness comparison between a synchronous and an asynchronous adder circuit.

Speaker Biography (Kok-Leong Chang)

Dr. Chang Kok-Leong received his B.Eng and Ph.D degrees in Electrical and Electronic Engineering from Nanyang Technological University, Singapore in 2004 and 2011, respectively. His Ph.D dissertation pertains to the design and fabrication of a process, voltage and temperature variation-robust microprocessor based on asynchronous logic for applications in ubiquitous sensors. He joined the Institute of Materials Research and Engineering in 2010 and is researching on asynchronous logic on variation-prone printed electronic applications. His research interests include microprocessor design, asynchronous logic and printed electronics.
