The purpose of this project was to begin the development and evaluation of a single channel electrophysiologic data acquisition system. The goal was to fabricate a bread board version of the system, develop an integrated circuit layout of the system, and develop a digital interface to the PC. The analog bread board was a single ended second order sigma-delta analog to digital converter and was digitally interfaced to the PC using a National Instruments Digital I/O board. A portion of the system, a switched-capacitor integrator which used a fully differential folded cascode op-amp, was designed using the NCSU 1.6um process library in Cadence Virtuoso for the integrated circuit.
