ABSTRACT
A brief overview of the fundamentals of S-D
analog-to-digital converters (ADC) will be presented
including theory, design methodologies, general characteristics, and
current trends. Due to the difficulty in linking integrator
performance to ADC performance, these non-linear circuits post serious
challenges to the designer in terms of optimizing designs. A
method that utilizes response surface sampling and genetic algorithms
is presented as one approach to linking integrator and ADC
performance. |

Don McGrath received his B.S.E.E. from Rochester Institute
of Technology, Rochester, NY, in 1986, his M.S.E.E. from Purdue University,
Lafayette, IN, in 1988, and his Ph.D.E.E. from Rensselaer Polytechnic
Institute, Troy, NY, in 1998. From 1988 to 2001, Dr. McGrath worked
at the General Electric Corporate R&D Center in Schenectady, NY, as a
mixed analog-digital designer. While at General Electric, his focus
was on the design of sigma-delta modulator analog-to-digital converters,
and their application to industrial and medical systems. In 2001, Dr. McGrath joined LSI Logic in Fort Collins, CO,
as Manager of Signal Processing Design. Since joining LSI Logic, his
focus has been on continuous-time filters and high-speed interface design. |
