该论文提出了一种200kS/s 13.5位集成磁通门差分磁数字转换器，通过过采样补偿环路解决了传统闭环磁通门读出电路带宽受限的问题，实现了nT级精度的磁场测量。
such as electric motor controllers, solar panel power inverters, electric vehicle battery chargers, uninterrupted and switching mode power supplies benefit from the galvanic isolation of contactless current sensors (CCS) [1]. These include magnetic sensors that sense the magnetic field emanating from a current-carrying conductor. The offset and resolution of Hall-effect sensors is in the μT-level [1-3], in contrast to the nT-level accuracy of integrated-fluxgate (IFG) magnetometers [4]. Previously reported sampled-data closed-loop IFG readouts have limited BWs as their sampling frequencies (fS) are limited to be less than or equal to the IFG excitation frequency, fEXC [5-7]. This paper describes a differential closed-loop IFG CCS with fS>fEXC. The differential
