Abstract

An integrated circuit device includes an active circuit component and a current sensor. The active circuit component may be coupled between a first conductive layer and a second conductive layer, and is configured to produce a first current. The current sensor is disposed over the active circuit component. The current sensor may includes a Magnetic Tunnel Junction (“MTJ”) core disposed between the first conductive layer and the second conductive layer. The MTJ core is configured to sense the first current and produce a second current based on the first current sensed at the MTJ core.
