  • Abstract
    A matched filter (MF) based upon the cascoded class AB SI technique is presented for spread-spectrum communication receivers. Accomplished through both architectural and circuit developments, the filter´s features include low power, high speed and compatibility with standard CMOS process inherent to SI signal processing. For performance assessment, a 31-tap 80 MS/s SI MF for despreading task in future high-speed WCDMA receivers is demonstrated.
