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.
