Design and Implementation of an analog to digital conversion mechanism for an in-situ monitoring microelectrode SOC

by Alla, Ravi Chandar

Abstract (Summary)
A lot of importance has been given to the problem of addressing the direct and indirect causes of the environmental pollution. Developing methods to effectively monitor and control pollution in the environment has been a major research area in recent years. Many sites containing toxic chemical spills and other waste materials from industries require constant and long term monitoring to reduce the detrimental impacts on public health.In-situ monitoring has gained a lot of importance and has become the most cost-effective and reliable way of monitoring the concentration of various toxicants. A system consisting of the microelectrode sensors with data-processing circuitry for analyzing the sample data at the remote user is essential for in-situ monitoring. This thesis work explains the development of an efficient analog to digital conversion mechanism for a second generation micro electrode SOC. This thesis work presents an efficient approach of the design of ADC for getting high resolution, low power and to consume less silicon area. The design has been fabricated in AMI 0.5 ยต m process at MOSIS fabrication facility. Results of the post silicon testing of the system and the ADC have been reported and the system is analyzed for performance. The results show that the analog to digital conversion mechanism designed can be used in the microelectrode SOC for in-situ environmental monitoring from 0.6 to 4.5 V providing 16 bit resolution.
