  • Omega and theta—a method to measure magnetic field at AC frequencies without using current spinning
    Patent number: 11940505
    Abstract: We use the AC Hall effect to characterize a magnetic field at an unknown frequency (or frequencies). The current to the Hall sensor is driven at a known frequency f. The output Hall voltage is characterized in a frequency range from f1 to f2 (with f<f1<f2 and f2?f1<2f). This provides a measurement of the magnetic field in a frequency range from f1?f to f2?f. The resulting measurement of magnetic field spectral components is phase-independent and requires no prior knowledge of exact magnetic field frequency.
