Researchers in Stanford University's EXtreme Environment Microsystems Laboratory (XLab) working in collaboration with the University of Arkansas' Mixed-Signal Computer-Aided Design (MSCAD) Laboratory developed a Hall-effect sensor design that detects ultra fast changes in the
Stanford University and University of Arkansas researchers in the XLab have developed a cost effective, 2dimensional electron gas (2DEG) Hall-effect magnetic field sensor that can operate from direct current to nearly Gigahertz frequencies.
Magnetic field measurements using currently available devices require complex switching circuitry to mitigate the offset and noise present in measurements.
