Abstract :
A spin-based analog-to-digital converter (ADC) using magnetic tunnel junctions (MTJs) is proposed in this letter. Our proposal is based on a novel high-speed low-power MTJ comparator that is controlled through spin Hall effect and voltage-controlled magnetic anisotropy effects. According to the simulation results, spin ADC offers features including high sampling rate, low-power consumption, and less chip area occupation for higher bit resolution while provides the benefit of nonvolatility of conversion results.
