A 2.3 GSample/s 10-tap digital FIR filter for magnetic recording read channels

A 6 b 10 tap 2.3 GSample/s distributed-arithmetic digital FIR filter uses footless dynamic logic with delayed reset for precharge. The 0.5 mm/sup 2/ filter, fabricated in 0.18 /spl mu/m CMOS, is operational from 1 V to 2 V power supply. At 2.3 GSample/s, the power is 680 mW, and at 1 GSample/s the p...

Zusammenfassung:A 6 b 10 tap 2.3 GSample/s distributed-arithmetic digital FIR filter uses footless dynamic logic with delayed reset for precharge. The 0.5 mm/sup 2/ filter, fabricated in 0.18 /spl mu/m CMOS, is operational from 1 V to 2 V power supply. At 2.3 GSample/s, the power is 680 mW, and at 1 GSample/s the power is 120 mW.
