ABSTRACT The challenges associated with integrating
digital controls in high-frequency switch-mode power supplies (SMPS)
will be outlined followed by details of recent research results that
demonstrate "all-digital" solutions. Key controller
blocks developed previously by Prof. Maksimovic at University of
Colorado will be introduced, including high-frequency digital
pulse-width modulators, fast delay-line A/D converters, and
hardware-accelerated computational units. Recent extensions of
these core blocks will be discussed including a chipset for isolated
DC-DC converters, high-performance power-factor-correction (PFC)
controllers, and intelligent electronic ballast controllers.
Time permitting, a brief highlight of the mixed-signal IC design
program (research and education) at the University of Colorado will be
given with a request for feedback on desired directions and course
content from local industry. |

Dragan Maksimovic
(M'89) received the B.S. and M.S degrees in electrical engineering
from the University of Belgrade, Yugoslavia, and the Ph.D. degree from
the California Institute of Technology, Pasadena, CA, in 1984, 1986,
and 1989, respectively. From 1989 to 1992, he was with the
University of Belgrade, Yugoslavia. Since 1992, he has been with
the Department of Electrical and Computer Engineering at the
University of Colorado, Boulder, where he is currently Associate
Professor and Co-Director of the Colorado Power Electronics Center (CoPEC).
His current research interests include simulation and control
techniques, mixed-signal integrated-circuit design for power
management applications, and power electronics for low-power portable
systems. |

Regan Zane received the B.S.,
M.S., and Ph.D. degrees in electrical engineering from the University
of Colorado, Boulder, in 1996, 1998, and 1999, respectively. He
is currently an assistant professor of electrical engineering at the
University of Colorado, Boulder. From 1999 to 2001, he worked as
a researcher at the General Electric Corporate R&D Center, where
he developed mixed-signal IC controllers for electronic
ballasts. In 2001, he joined the faculty of the University of
Colorado and became a research advisor at the Colorado Power
Electronics Center. His research interests include mixed-signal
IC design for power converters, modeling and analysis of switching
converters, and power generation and management in low-power wireless
systems.
