摘要
A device and method are provided for reducing impedance, impedance discontinuities, and signal-loop area in flex cables used for a signal path. In one embodiment of the invention, a flex cable is provided for reducing the impedance and length of a return-signal path. The flex cable includes a signal conductor, and a return-signal conductor not connected to ground. The flex cable may also include a ground conductor. Such a flex cable provides a shorter- and lower-impedance return-signal path between a signal source and receiver than do conventional flex cables. In another embodiment of the invention, a method is provided that includes the steps of delivering a signal from a signal source to a signal receiver with a flexible conductor, and returning the signal from the signal receiver to the signal source with another flexible conductor other than ground.
