Zusammenfassung:Techniques are provided for sensing a first current produced by an active circuit component. According to these techniques, a current sensor is disposed over the active circuit component. The current sensor includes a Magnetic Tunnel Junction ("MTJ") core disposed between a first conductive layer and a second conductive layer. The MTJ core can be used to sense the first current and produce a second current based on the first current sensed at the MTJ core.
