has been fully implemented in Verilog-A, enabling its direct use in STO-based systems. During the implementation, an approach to replicate the phase noise, hence the generated signal of the MTJ STOs, has been developed. This approach makes a reliable MTJ STO model possible, and allows different performance analyses so as to extensively explore possible applications. The simulation results of the stand-alone MTJ STO model and the MTJ STO-based system show that the implemented model gives identical characteristics as those obtained from the proposed analytical model. Additionally, the results demonstrate that the proposed MTJ STO model is useful for estimating as well as improving overall performance of the MTJ STO-based circuits and systems. Consequently, the proposed MTJ STO has the potential to accelerate the development of MTJ STO technology towards its future applications.
