COMMON-MODE SUPPRESSOR BASED ON DIFFERENTIAL TRANSMISSION LINE |
| 摘要 |
A common-mode suppressor for eliminating common-mode noise in high frequency differential data transmission systems and an associated method includes a long coiled differential transmission line configured to transfer data between a source and a load. The differential transmission line comprises a first conductive wire and a second conductive wire which are inductively and capacitively coupled and are laterally aligned or vertically aligned with each other. Further, the differential transmission line is matched for differential signals and un-matched for common-mode noise. |

1. A differential data transmission system, comprising:
a source circuit configured to transmit a differential signal containing data; a load circuit configured to receive the differential signal; and a common-mode suppressor comprising a long, coiled differential transmission line configured to transfer the differential signal from the source circuit to the load circuit; wherein a length of the differential transmission line is at least greater than one-tenth of the wavelength of the differential signal being transmitted through the differential transmission lines for a predetermined operating frequency range of the differential signal to establish a distributed system model for the common-mode suppressor. |
