Abstract

We propose a new compact MTJ model for circuit simulation which is implemented by Verilog-A and can be easily built in de-facto standard SPICE. The model is based on switching probability of an MTJ with time-varying input current. The transition between the adiabatic precessional model and the thermal activation model is made smooth by using an interpolation function with a technique to predict a switching time from an input current. Simulation results validate that the model is consistent with physical model and effective for MTJ/CMOS hybrid circuit simulation.
