Abstract
An improved method and design for adjusting clock skew in a wire trace is disclosed. Aspects of the invention include a corrugated pattern wire trace bracketed by a pair of parallel conducting wire frames with wire extensions projecting between the corrugations of the wire trace. The wire frames are connected to a voltage supply. The transmission properties of the wire trace, and thus the degree of clock skew associated with the wire trace, are affected by the number of wire extensions protruding between the corrugations, their degree of penetration, as well as other factors inherent in the design. The present design can achieve the same degree of clock skew with a smaller surface area covered and with fewer resistive losses than with prior art designs.
