Fault diagnosis and redesign of a 12-bit successive approximation analog-to-digital converter

Project (M.S., Electrical and Electronic Engineering) -- California State University, Sacramento, 2013.The objective of this project was to debug and redesign as needed an existing but broken 12-bit successive approximation analog-to-digital converter (SA ADC) for use in an analog front-end integrated circuit in an electrocardiogram monitoring application. The simulation results initially obtained for the SA ADC showed that the converter obtained roughly 6-bit resolution. The redesign effort included correcting problems found in the connections for the reference voltage and biasing circuits, as well as redesigning the successive approximation digital logic.Electrical and Electronic Engineerin
