Design and Analysis of a Transversal Filter RFIC in SiGe Technology

Filters are a critical component of every high-speed data communications system. Die area, power consumption, and RFIC integration are primary concerns for filter designers. The authors of this article have designed and fabricated a low-power analog filter with greatly reduced die area compared to passive delay lines. This transversal filter design has been realized in 47-GHz SiGe process technology.
