Title (EN) ALL-DIGITAL NOISE CANCELLATION METHOD FOR SOLID STATE SPIN-BASED SENSORS
(FR) PROCÉDÉ D'ANNULATION DE BRUIT ENTIÈREMENT NUMÉRIQUE DESTINÉ À DES CAPTEURS À SEMI-CONDUCTEURS BASÉS SUR LE SPIN
Abstract:
(EN) Embodiments of the present disclosure relate to systems and methods for noise cancellation and deriving a physical quantity measurement. In accordance with certain embodiments, a noise cancellation system for a solid state spin sensor can include an analog to digital converter that converts a reference waveform into at least one digitized reference waveform, and converts a signal waveform into at least one digitized signal waveform. The noise cancellation system for a solid state spin sensor can include a processor that receives the at least one digitized reference waveform and the at least one digitized signal waveform. The processor may calculate a corrected signal waveform using the at least one digitized reference waveform and the at least one digitized signal waveform, and derive a measurement of a physical quantity from the corrected signal waveform.
(FR) La présente invention concerne, selon des modes de réalisation, des systèmes et des procédés d'annulation de bruit et de dérivation d'une mesure de quantité physique. Selon certains modes de réalisation, un système d'annulation de bruit destiné à un capteur de spin à semi-conducteurs peut comprendre un convertisseur analogique-numérique qui convertit une forme d'onde de référence en au moins une forme d'onde de référence numérisée, et qui convertit une forme d'onde de signal en au moins une forme d'onde de signal numérisée. Le système d'annulation de bruit destiné à un capteur de spin à semi-conducteurs peut comprendre un processeur qui reçoit la ou les formes d'onde de référence numérisées et la ou les formes d'onde de signal numérisées. Le processeur peut calculer une forme d'onde de signal corrigée, à l'aide de la ou des formes d'onde de référence numérisées et de la ou des formes d'onde de signal numérisées, et peut déduire une mesure d'une quantité physique à partir de la forme d'onde de signal corrigée.
