Abstract
A current sensor includes: several magnetic-field-sensitive components which are disposed on a support such as to be distributed around a conductor through which a current to be measured flows, and a processing circuit which receives an output signal from the components, each component having at least one first terminal which is connected to a summing point by a summing resistor and a second terminal which is connected to a common point. Moreover, all of the resistors are connected to a first conductor which is connected to the summing point and all of the second terminals are connected to a second conductor which is connected to the common point. The support includes a printed circuit, while the two conductors include conductor tracks of the printed circuit, which are routed in a zigzag manner on the printed circuit such as to form a bunched or braided conductor.
