High-pssr differential fast switching coil driver

A sensor, comprising:

• one or more magnetic field sensing elements that are configured to generate a sensing signal, the sensing signal being indicative of a strength of a magnetic field that is incident on the one or more magnetic field sensing elements;
• a processing circuitry that is configured to generate an output signal based on the sensing signal;
• and
• a first amplifier that is configured to drive a first coil based on the sensing signal, the first coil being coupled in a first negative feedback loop of the first amplifier,
• wherein the first negative feedback loop spans between a first input terminal of the first amplifier and a first output terminal of the first amplifier, and
• wherein the sensing signal is, at least in part, applied at the first input terminals of the first amplifier.
