A current probe enabling measurement of current of a signal in a circuit includes a ferrite core defining a gap, a wire wrapped around the ferrite core and a magnetic field sensor. The wire is configured to receive the signal from the circuit, where the current of the signal flowing in the wire generates a magnetic field in the ferrite core. The magnetic field sensor is positioned in the gap of the ferrite core, the magnetic field generated in the ferrite core flowing through the magnetic field sensor, which produces a voltage proportional to an intensity of the magnetic field. The current is measured based on the voltage produced by the magnetic field sensor.
