Common mode field rejection magnetic current sensor

A current measurement system, comprising:

• an electrically conductive strip extending along a first direction and configured to pass a signal current to be measured along the first direction;
• a first magnetic sensor and a second magnetic sensor, wherein each magnetic sensor is configured to output an output signal according to a signal magnetic field that is generated by the signal current;
• wherein the strip comprises a first notch, extending from a first lateral side of the strip, along a second direction substantially perpendicular to the first direction and forming a first edge and a second edge on each side of the first notch along the second direction;
• such that, in a first zone of the strip bordering the first edge, the signal current comprises a first current portion flowing substantially in the second direction and generates a first signal magnetic field with a first polarity;
• and in a second zone of the strip bordering the second edge, the signal current comprises a second current portion flowing substantially in the second direction and generating a second signal magnetic field with a second polarity opposed to the first polarity;
• wherein the first magnetic sensor is arranged in the first zone to outputs a first output signal according to the first signal magnetic field, and the second magnetic sensor is arranged in the second zone to outputs a second output signal according to the second signal magnetic field, the output signal corresponding to the difference between the first and the second output signals.
