Abstract: Disclosed is a current sensor (600) that senses current flow in a conductor (604) by coupling a first magnetic field generated by the conductor to a sense element (602). The current sensor includes a shield (700) including a first material (702a,702b) that sandwiches the sense element to define a stack and a second material (704a,704b) that sandwiches the stack. The shield is configured to generate a second magnetic field, responsive to a third magnetic field external to the current sensor that opposes the third magnetic field. The shield is further configured to prevent production of a magnetic field that opposes the first magnetic field generated by the flow of current in the conductor.
