    Abstract: 所揭露的是一種靜電放電(ESD)保護電路,其能夠藉由降低該電路的電容來實現差動信號的加快速度。傳輸線係連接至一IN端與一 端並且差動信號係輸入至該等端,該ESD保護電路係連接至該等傳輸線並保護一內部電路免於施加至該IN端與該 端的一突波電壓,該ESD保護電路的一對電晶體係形成在相同的井中。因此,當差動信號通過時,保持在轉變之前的一狀態之該對電晶體的汲極中的電荷在相同的井中轉移。結果,該對電晶體的汲極中的電容係有關差動信號的轉變而被降低以至於差動信號的加快速度能被實現。

    Abstract: 一種阻抗轉換裝置具有四個導體,這些導體經配置而使得第一與第二導體形成具有第一特徵阻抗之傳輸線;第三與第四導體形成具有第一特徵阻抗之傳輸線;第一與第三導體形成具有第二特徵阻抗之傳輸線;且第二與第四導體形成具有第二特徵阻抗之傳輸線。第二與第四導體是經由等於第一特徵阻抗之電阻而互連於鄰近末端處。第三與第四導體是經由等於第二特徵阻抗之電阻而互連於鄰近末端處。阻抗轉換裝置之橫向尺寸足夠小以允許插入於疊對線中。 An impedance conversion device has four conductors arranged so thatthe first and second conductors form a transmission line having a first characteristic impedance, the third and fourth conductors form a transmission line having the first characteristic impedance, the first and third conductors form a transmission line having a second characteristic impedance, and the second and fourth conductors form a third transmission line having the second characteristic impedance. The second and fourth conductors are interconnected at proximate ends through a resistance equal to the first characteristic impedance. The third and fourth conductors are interconnected at proximate ends through a resistance equal to the second characteristic impedance. The lateral dimensions of the impedance conversion device are small enough to permit insertion in a stacked pair line.
