Abstract
According to some embodiments, a sensor includes: one or more sensing elements configured to generate a magnetic field signal having a magnetic field component that varies in response to a magnetic field and an offset component contributed by the one or more sensing elements; a modulation circuit configured to modulate the magnetic field component of the magnetic field signal at a modulation frequency; an amplifier configured to receive the modulated signal and provide an amplified modulated signal having a current responsive to at least the magnetic field and the offset contributed by the one or more sensing elements; and a sample and hold circuit configured to receive the amplified modulated signal and provide a conditioned signal having a current that varies in response to the magnetic field signal and having substantially zero offset contribution from the one or more sensing elements and from the amplifier.
