Abstract

This paper presents the design of a K=3, 2Mbps Turbo decoder chip targeted for 3rd generation wideband CDMA (W-CDMA) systems. This paper makes two contributions. First, finite precision effects on the decoder performance are analyzed and optimal word-lengths are determined. Second, novel power-down techniques are proposed, with which very high power-down efficiency can be achieved without significant performance degradation. The decoder has been designed and fabricated using a 0.25μm standard cell library. The core size is 2.32mm×1.72mm and contains 300K transistors.
