In this thesis work, a design of 14-bit, 20MS/s segmented digital-to-analog converter (DAC) is presented. The segmented DAC uses switched-capacitor configuration to implement 8 (LSB) + 6 (MSB) segmented architecture to achieve high performance for minimum area. The implemented LSB DAC is based on quasi-passive pipelined DAC that has been...
A single item is to be produced over a given number of time
periods to satisfy the future requirements which are subject to fluctuations.
The production rate and work force level for each time
period are to be decided in order to minimize the production cost
where the costs for...
Delta-Sigma (ΔΣ) analog-to-digital converters (ADCs) are traditionally used in high quality audio systems, instrumentation and measurement (I&M) and biomedical devices. With the continued downscaling of CMOS technology, they are becoming popular in wideband applications such as wireless and wired communication systems,high-definition television and radar systems. There are two general realizations...
Consumption of raw oysters has been linked to several outbreaks of Vibrio parahaemolyticus
infection in the United States. This study investigated effects of ice storage and UV-sterilized
seawater depuration at various temperatures on reducing V. parahaemolyticus in oysters. Raw
Pacific oysters (Crassostrea gigas) were inoculated with a mixed culture of...
Only two genome-wide significant loci associated with longevity have been identified so far, probably because of insufficient sample sizes of centenarians, whose genomes may harbor genetic variants associated with health and longevity. Here we report a genome-wide association study (GWAS) of Han Chinese with a sample size 2.7 times the...
