In this paper, we propose a new 3-bit ADC based on magnetoelectric spin–orbit (MESO) device. By adjusting the thickness of the magnetoelectric part of MESOs, the ADC possesses multiple switching thresholds for converting input voltages into magnetization state. By means of the iterative HSPICE analysis and Monte Carlo analysis, we quantitatively calculated the power consumption and evaluated the reliability of the ADC device. The results show that the proposed ADC could sample at an 8.3 GHz rate with 0.014 pJ conversion energy. In comparison with the NAND-SPIN based magnetic ADC (MADC), the sampling rate and power of the proposed ADC could be improved by 66% and economize up to 45.3% respectively.

在本文中，我们提出了一种基于磁电自旋轨道 (MESO) 器件的新型 3 位 ADC。通过调整 MESO 磁电部分的厚度，ADC 具有多个开关阈值，用于将输入电压转换为磁化状态。通过迭代HSPICE分析和蒙特卡罗分析，我们定量计算了ADC器件的功耗并评估了其可靠性。结果表明，所提出的 ADC 可以以 8.3 GHz 的速率进行采样，转换能量为 0.014 pJ。与基于 NAND-SPIN 的磁性 ADC (MADC) 相比，所提出的 ADC 的采样率和功耗可分别提高 66% 和节省高达 45.3%。
