Matched integrated electronic components
Abstract:
A switchable integrated electronic device includes at least three elements r1 . . . r14, s1 . . . s14 series coupled in a chain between a first port and a second port and includes a node between successive elements r1 . . . r14, s1 . . . s14 of the chain. There is a switch means for coupling a selectable one of the nodes to a third port. If successive elements r1 . . . r14, s1 . . . s14 in the chain are denoted ri, i=1 to N, and if adjacent positions occupied by the elements are numbered consecutively 1 to N, then element ri occupies position ⌊ N + 1 2 ⌋ + ( - 1 ) i · 2 · ⌊ i 2 ⌋ ⁢ ⁢ ⁢ for ⁢ ⁢ i = 1 ⁢ ⁢ to ⁢ ⁢ ⌊ N 2 ⌋ and position ⌊ N + 1 2 ⌋ + ( - 1 ) i · ( 2 · ⌊ N - i 2 ⌋ + 1 ) ⁢ ⁢ for ⁢ ⁢ i = ⌊ N 2 ⌋ + 1 ⁢ ⁢ to ⁢ ⁢ N .
Abstract(Chinese):

可切换的集成电子设备包括至少三个元件r1。 。 。 r14，s1。 。 。 s14系列耦合在第一端口和第二端口之间的链路中，并且包括连续元件r1之间的节点。 。 。 r14，s1。 。 。 s14的链。 存在用于将可选择的一个节点耦合到第三端口的开关装置。 如果连续元素r1。 。 。 r14，s1。 。 。 链中的s14表示为ri，i = 1〜N，如果元素所占据的相邻位置连续编号为1〜N，则元素ri占据位置⌊N + 1 2⌋+（ - 1）i·2·⌊ i 2⌋⁢⁢⁢⁢i⌊⌊⌊⌋⌊⌊⌊N + 1 2⌋+（ - 1）i·（2·⌊N - i 2⌋+ 1） for唔i =⌊N 2⌋+ 1⁢to⁢N。
