Abstract
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.
