Low-power and compact CDMA matched filters have been developed based on the floating-gate MOS technology. The low-power operation has been achieved by employing the single-step matching scheme and disconnecting the coupling-capacitors unnecessary for the matching operation. The 255-chip matched filter fabricated in a 0.35-μm technology demonstrated 6 mW operation at 3 V power supply and the chip rate of 5 MS/S, while occupying the chip area of 1.0 mm2.
