                                ABSTRACT

Delay Coordination Method (DCM) is a timing methodology for clock and
data delay coordination that produce very high performance integrated
circuits. In this methodology, control of differential path delays
combined with careful management of clock skew and data events are
the key to obtaining maximum performance from digital VLSI circuits.
This is a new way of comprehending fundamental performance limits of
a given technology and allows the digital designer to exploit intrinsic
device matching properties of integrated circuits normally used by
the analog designer.

DCM in CMOS have been significantly developed at North Carolina State
University. In this seminar, we will present the underlined theory,
design requirement, technology limitation, circuit technique, and
implementation examples such as adder, digital sampler, and data/clock
recovery.

Dr. Wentai Liu received his PhD degree in computer engineering from
University of Michigan, Ann Arbor, Michigan, in 1983. Since 1983, he
has been on the faculty of North Carolina State University, where he
is currently an Associate Professor of Electrical and Computer
Engineering. His main research interests are high-speed VLSI design/CAD,
microelectronic sensor design, and high-speed communication netowrks.
