The multiplication operation is one of the most used, but also one of the most energy-expensive operations in digital systems. Here, we focus on a promising strategy to perform the analog multiplication which is based on the use of two coupled spin-torque oscillators (STOs) using the concept of Degree of Match (DOM). The study is based on the theory of non-linear auto-oscillators with negative damping universally used for STOs. The robustness of the DOM is assessed with respect to the variability and noise perturbances parameters.

Abstract
The multiplication operation is one of the most used, but also one of the most energy-expensive operations in digital systems. Here, we focus on a promising strategy to perform the analog multiplication which is based on the use of two coupled spin-torque oscillators (STOs) using the concept of Degree of Match (DOM). The study is based on the theory of non-linear auto-oscillators with negative damping universally used for STOs. The robustness of the DOM is assessed with respect to the variability and noise perturbances parameters.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
