 技術摘要 / Our Technology： |
一種電磁雜訊抑制裝置，其係於高電壓平面層與低電壓平面層之間，以週期性排列佈設複數個具有中心對稱之環型連通柱晶體單元，即可形成一層可抑制雜訊干擾及電磁波向外傳播的電磁雜訊截止帶。其中，環型連通柱晶體單元又有兩種設置方式，一種係以複數個連通柱垂直連接於一金屬平面層與該低電壓平面層之間；另一種則是以複數個連通柱垂直連接兩金屬平面層。於此可知，本發明利用週期性擺放連通柱晶體之設計，取代習知技術中採用耦合電容或是高介電常數的昂貴晶體材料，即可產生一良好的雜訊干擾截止帶，進而大幅降低電源平面之設計複雜度與其生產成本。
Proposed is an apparatus for silencing electromagnetic noise, characterized by a plurality of centrally symmetrical ring-shaped through-via-hole crystalline units provided between a high voltage plane and a low voltage plane at a regular interval, thereby forming an omnidirectional noise suppression frequency band for reducing noise interference and electromagnetic radiation. In a first embodiment of the ring-shaped through-via-hole crystalline units, the through via holes are perpendicularly coupled between a metal plane and the low voltage plane. In a second embodiment of the ring-shaped through-via-hole crystalline units, the through via holes are perpendicularly coupled between two metal planes. Positioned at a regular interval, the through via holes enable provision of omnidirectional noise suppression frequency band, simplified design of a power plane, and reduction of production costs.
