Abstract
This paper describes the design of multirate filters used for the sample rate reduction of digital signals and their implementation on mixed-signal integrated circuits. Reaching target specifications of power, speed and silicon area as well as realizing multi-mode operation presents challenges. Possible solutions are discussed particularly for those filter stages which operate at the high sample rates and are illustrated in examples.
Zusammenfassung
Dieser Artikel beschreibt den Entwurf von Multiratenfiltern zur Reduktion der Taktrate digitaler Signale in gemischt analog-digitalen ICs. Die Realisierung von Systemanforderungen im Bereich der Leistungsaufnahme, der Taktrate und Siliziumfläche sowie eines Multimode-Betriebs stellt dabei eine besondere Herausforderung dar. Lösungsansätze speziell für jene Filterstufen, die mit den hohen Taktraten arbeiten, werden anhand von Beispielen beschrieben.
