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.
