Energy efficiency plays an important role in the design of high performance analog and mixed-signal CMOS circuits such as, for example, analog-to-digital converters (ADCs). In high accuracy ADCs, it is becoming increasingly difficult to maintain energy efficiency as CMOS technology is scaled to nanometer dimensions. In this talk important challenges often faced by analog designers working with nanoscale CMOS technologies are discussed and measures for mitigating some of the scaling effects are presented and verified in terms of measured performance of fabricated prototypes.


Trond Ytterdal received his M.Sc. and Ph.D. degrees in electrical engineering from the Norwegian Institute of Technology in 1990 and 1995, respectively. He was employed as a research associate at the University of Virginia (1995-1996) and as a research scientist at Rensselaer Polytechnic Institute in Troy, New York (1996-1997). From 1997 to 2001 he worked as an ASIC designer at Nordic Semiconductor in Trondheim, Norway. Since 2001 he has been on the faculty of the Norwegian University of Science and Technology (NTNU), where he is a Professor at the Department of Electronic Systems. He has authored or co-authored more than 200 papers and is a co-developer of the circuit simulator AIM-Spice. His current research interests include: Design of analog integrated circuits, behavioral modeling and simulation of mixed-signal systems, modeling of nanoscale transistors and novel device structures. Prof. Ytterdal is a member of The Norwegian Academy of Technological Sciences and a Senior Member of IEEE.
