We have implemented a switched current matched filter (SIMF) LSI for the synchronization channel of IMT-2000. A partial correlation structure has been proposed for reducing current-transfer-error accumulation, which degrades correlation dynamic range. Degradation of correlation dynamic range can be improved 1.8dB at the current transfer error of 1%. Power consumption of 7.5mW has been estimated with 93% current-cut. 64chip SIMF has been fabricated using 0.8μm CMOS process. The correlation peaks can be clearly observed at the chip rate of 4Mcps. 0.2-dB degradation of probability of synchronization error has been obtained.
