Abstract: Removing common-mode current from a pair of complementary current signals, including: generating a common-mode voltage of the pair of complementary current signals including at least a first current signal and a second current signal; measuring and outputting a difference voltage between the generated common-mode voltage and a common-mode reference voltage; and removing at least a portion of the common-mode current from the first current signal and the second current signal based on the difference voltage.
Abstract translation: 从一对互补电流信号中去除共模电流，包括：产生包括至少第一电流信号和第二电流信号的一对互补电流信号的共模电压; 测量并输出所产生的共模电压和共模参考电压之间的差分电压; 以及基于所述差电压从所述第一电流信号和所述第二电流信号中去除所述共模电流的至少一部分。
