Abstract: A method of sensing a current in a conductor includes controlling a digital to analog converter output to cancel residual offset voltage in a magnetic tunnel junction device prior to sensing the current with the magnetic tunnel junction device. The method includes switching input to the magnetic tunnel junction device between a fixed voltage and an output of a digital to analog converter while switching input to a band pass filter between a lower and an upper voltage output of the magnetic tunnel junction device. The output of the digital to analog converter is modified to provide a low-amplitude unsaturated sine-wave at an output of the band pass filter, at which point changes in the output of the band pass filter are associated with the amount of current in a sensed conductor.

In the first step, a charge current through heavy metal (HM) places the magnetization of a nano-magnet along the hard-axis (i.e. an unstable point for the magnet).

The polarity of the net synaptic current determines the final orientation of the magnetization. A resistive crossbar array may also be provided which functions as the synapse generating a bipolar current that is a weighted sum of the inputs of the device.
