Analog CMOS Interface Circuits for UMSI Chip of Environmental Monitoring Microsystem

Abstract

The objective of this project has been to implement the analog interface circuitry of the UMSI chip for the Environmental Monitoring Microsystem. This circuitry provides the readout for capacitive sensors, a resistive sensor, and interface for sensors with direct voltage output. The analog interface circuit block is highly programmable and provides offset and gain adjustments. It also supports self-test for physical capacitive sensors. This report describes the general architecture and detailed description of the design. Also simulated performance of the circuit is presented.
