| 摘要 |
TRANSMISSION LINE IMPEDANCE MATCHING IS DESCRIBED FOR MATCHING AN IMPEDANCE DISCONTINUITY ON A TRANSMISSION SIGNAL TRACE. THE APPARATUS INCLUDES A TRANSMISSION SIGNAL TRACE AND A NON-TRANSMISSION TRACE. THE TRANSMISSION SIGNAL TRACE HAS AN IMPEDANCE DISCONTINUITY, A FIRST LENGTH, AND A PREDETERMINED FIRST WIDTH. THE NON-TRANSMISSION TRACE IS DISPOSED NEAR THE TRANSMISSION SIGNAL TRACE AT A REGION CORRESPONDING TO THE IMPEDANCE DISCONTINUITY. THE NON-TRANSMISSION TRACE HAS A SECOND LENGTH THAT IS SUBSTANTIALLY LESS THAN THE FIRST LENGTH OF THE TRANSMISSION SIGNAL TRACE. ADDITIONALLY, THE NON-TRANSMISSION TRACE IS CONFIGURED TO BE ELECTROMAGNETICALLY COUPLED TO THE TRANSMISSION SIGNAL TRACE IN THE PRESENCE OF A CURRENT ON THE TRANSMISSION SIGNAL TRACE TO PROVIDE A MATCHED IMPEDANCE ON THE TRANSMISSION SIGNAL TRACE.
