Abstract

This paper presents a low power 8-tap digital Fourier infrared (FIR) filter for partial response signalling with maximum likelihood (PRML) disk-drive read channels. Enhancements on power consumption and speed are achieved by adopting the row compression scheme with a proposed conditional carry selection method. The 8-tap digital FIR filter is fabricated by 0.8 μm CMOS technology and occupies by 3.9mm × 1.5mm. The experimental results show that the FIR filter operates up to 180MHz and dissipates 1.4mW Mhz-1 with 3.7V power supply. It is proved that 20% power reduction is readily attainable with the proposed scheme.
