Abstract
A reference circuit for generating a reference current includes a plurality of resistive elements including at least one magnetic tunnel junction (MTJ). A control circuit is coupled to a first terminal of the at least one MTJ and is configured to selectively flow current through the at least one MTJ in the forward and inverse direction to generate a reference current.
