Compensation of Interconnect Line Degradations by Negative Group Delay Active Circuit
Abstract
Nowadays, because of the continuous technological progress in the very deep-submicron area, the overall circuit performance is dominated by interconnect delay. So, the interconnect line propagation delay can no longer be neglected. The most popular among the theoretical models available in the literature to assess the effects of these lines has been proposed by Elmore in 1948. We recently developed an active circuit able to produce negative group delay (NGD) and gain at first in the microwave domain, and secondly dedicated to base band signals. Thanks to this new concept, we proposed an innovative technique to reduce interconnect effects.
