Signal Processing via FPGAs to Facilitate Signal Generation for A Portable Mass Spectrometer (2012)

Undergraduates: Rocco DiSanto, none none none


Faculty Advisor: Collin McKinney
Department: Applied Sciences


The objective of this research project is to develop a digital control system to precisely regulate the high frequency electrical input to a portable mass spectrometer. A waveform in the low megahertz range is desired with amplitude resolution of better than one part per thousand. The system utilizes digital signal processing algorithms implemented in a field programmable gate array (FPGA) and high speed, high resolution analog-to-digital and digital-to-analog converters to achieve design requirements. The digital signal processing algorithms under development are designed to precisely control signal amplitude as well as compensate for nonlinearities in other system amplifiers.
