Magnetic tunnel junction model in Verilog-A for use in CAD environments for integrated circuits

Abstract

Electrical model of a magnetic tunnel junction is developed in Verilog-A language, which can use in CAD systems to design an integrated circuit of spintronics devices. In order to check the correct operation of the model verification tests were created and carried out in Cadence ADE. Each test corresponds to the operating mode of the magnetic tunnel junction: switching, generation, rectification. Thus, the developed model can be used to simulate hybrid circuits comprising CMOS elements and magnetic tunnel junctions.
