| 摘要 |
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. |

1. A circuit for removing common-mode current from a pair of complementary current signals, the circuit comprising:
a generator unit configured to generate a common-mode voltage of the pair of complementary current signals comprising at least a first current signal and a second current signal; and a measurement unit configured to measure and output a difference voltage configured to remove the common-mode current from the first current signal and the second current signal, wherein the difference voltage is based on a difference between the common-mode voltage generated by the generator unit and a common-mode reference voltage. |
