Harnessing Power and Variability of Analog Circuits in Scaled CMOS

As technology scaling approaches the fundamental physical limit, the inevitable consequences of such scaling on integrated-circuit performance have been the limelight of research and development lately in academia and industry. Since elevated process variations and reduced supply voltages present fundamental challenges to implement high-performance CMOS circuits in deeply scaled process nodes, one cannot help asking: can we keep benefiting from scaling? What comes to rescue the roadmap? In this talk, after identifying a few critical needs of the IC industry, I will examine some fundamental issues associated with the design of analog-digital interface circuits. As more and more realized by the analog community, it appears that system-level techniques increasingly play a key role in implementing critical analog functionalities in future technologies. A few design examples will also be given to showcase, here in the middle of nowhere, the ongoing research activities and the projects we pursue in analog circuit design
