EMI SUPPRESSION TECHNIQUE USING A TRANSMISSION LINE GRATING |
| 摘要 |
The present invention proposes methods and structures for designing electronic circuit elements for frequency suppression of electromagnetic waves using a transmission line grating. The method includes determining a frequency to be suppressed. Using the electrical wavelength of the frequency to be suppressed, determine a length of a plurality of equal length sections of the differential transmission lines is determined. Using the frequency to be suppressed and the electronic circuit requirements, determine a set of properties for the plurality of equal length sections of the differential transmission lines. The transmission line grating is created using a plurality of alternating equal length sections of the differential transmission lines. |

1. A method of designing electronic circuit elements for frequency suppression of electromagnetic waves using a transmission line grating, the method comprising:
determining a frequency to be suppressed; determining, in response to an electrical wavelength of the frequency to be suppressed, a length of a plurality of equal length sections of the differential transmission lines; utilizing the frequency to be suppressed and in response to electronic circuit requirements, determine a set of properties for the plurality of equal length sections of the differential transmission lines; and creating the transmission line grating with a plurality of alternating equal length sections of the differential transmission lines. |
