T9: Design of Voltage References
Voltage references are indispensable components in IC design. Their applications
range from simple biasing to providing adequate accuracy for ADCs, DACs,
VFCs, and other building blocks. In this tutorial, bandgap reference (BGR) fundamentals
and the design of CMOS BGRs will be covered. Topics include classic
BGRs, op-amp based and non-op-amp based BGRs; BGRs with and without
output buffers; stability issues arose from negative and positive feedback; loopgain
function and power-supply rejection; startup issues, trimming and design
of resistor strings. Advanced topics include curvature compensation, sub-1V references,
micro-power references, and alternatives to bandgap references such
as fully CMOS references and resistor-less references.
Instructor: Wing-Hung Ki
Wing-Hung Ki received his B.Sc. from UCSD (1984), M.Sc.
from Caltech (1985), and Ph.D. from UCLA (1995), all in
electrical engineering. From 1992 to 1995, he worked for
Micro Linear, San Jose, on the design of power converter
controllers. He joined the Hong Kong University of Science
and Technology (HKUST) in 1995, and is currently a professor
of the Department of Electronic and Computer
Engineering. His research interests are IC techniques for
power management circuits, power transponders for RFID
and energy harvesting applications, and fundamental research in switching converters
and charge pumps.
