N2 - Spintronic oscillators are nanodevices that are serious candidates for CMOS integration due to their compactness and easy frequency tunability. Among them vortex-based oscillators appear as one of the most promising technology because of their lower power supply and higher quality factors. To assess their potential in circuits and systems, compact models describing their behavior are necessary. In this work, we propose an implementation of a spintronic nano-oscillator (STNO) model for integrated circuit (IC) architectures design. The modeled device is a vortex-based magnetic oscillator demonstrating self-sustained magnetization oscillations under current bias, inducing alternating voltage across the device. This model describes the coupled electrical and magnetic behavior of the device, taking into account phase and amplitude noises associated with thermal fluctuations. Compatibility with commercial CMOS design kits is demonstrated, and an implementation in a CMOS circuit is proposed for AC signal generation. These results will allow to develop and evaluate innovative hybrid STNO/CMOS systems and their potential to efficiently complement existing full-CMOS technologies.
