该论文提出了一种采用占空比循环技术的集成磁通门磁力计，用于接触式电流传感，实现了770 kS/s的采样率。通过占空比循环显著降低了功耗，同时保持了nT级的分辨率，解决了高电压应用中传统磁传感器功耗高的问题。
Instruments, Freising, Germany 4 Kilby Labs, Texas Instruments, Santa Clara, CA 1 2 Electric vehicle battery chargers, solar-panel inverters, industrial power monitoring, and many other high voltage applications rely on magnetic sensors for contactless current sensing over shunt-based sensors due to inherent galvanic isolation [1-4]. Within magnetometers, integrated fluxgate (IFG) sensors provide nT resolution versus μT accuracy of Hall sensors [1-4]. To linearize IFG response, magnetic fields are balanced out in the core using large compensation currents at high fields, making them power hungry (>100mW for 2mT) [1,2]. Previous IFG sensors were designed for continuous operation at high sampling rates, but with long initial convergence time (200µs),
