  • Publication number: 20160248423
    Abstract: A feedthrough signal transmission apparatus, fabricated on a single silicon, includes a plurality of feedthrough signal transmission circuits and a permanently on control cell that is coupled to the feedthrough signal transmission circuits, where each feedthrough signal transmission circuit of the feedthrough signal transmission circuits may include at least one sub-circuit that is kept in a power on state when the sub-circuit performs feedthrough signal transmission. For example, and the sub-circuit may include a permanently on-for-feedthrough repeater (e.g. a repeater that is kept in the power on state when the repeater performs feedthrough signal transmission). In addition, the permanently on control cell may be configured to maintain the power on state of the sub-circuit when the sub-circuit performs feedthrough signal transmission. For example, sub-circuits of the feedthrough signal transmission circuits are located at grid-based locations, respectively.
