Abstract

The study focuses on analyzing the frequency-dependent performance of an all-spin logic (ASL) circuit. The ASL circuit model is simulated using (i) stochastic Landau-Lifshitz-Gilbert (sLLG) equation to capture the magnetization dynamics, (ii) spin drift-diffusion equation to describe the spin transport, and (iii) spin modified circuit analysis to formalize a schematic diagram for the ASL circuit. From the generated output spin current, the ASL circuit works well with its logic switch capability demonstrated as a logic buffer and inverter. A frequency sweep analysis is employed to obtain the operating frequency performance parameter where the decay range on its output clock rate is determined. From here, a linear fit is used to obtain the critical frequency, which is found to be fc =0.31770±0.00006 GHz. This serves as an implication of a figure of merit for the ASL circuit.
