A low-power 170-MHz discrete-time analog FIR filter

A 170-MHz analog finite impulse response (FIR) filter operating from a single 3.3-V supply is described. The design has been fabricated in the HP 1.2-/spl mu/m CMOS process and has an area of 2.35 mm by 1.97 mm including bonding pads. This 9-tap filter dissipates 70 mW when operating at 170 MHz. The...

Zusammenfassung:A 170-MHz analog finite impulse response (FIR) filter operating from a single 3.3-V supply is described. The design has been fabricated in the HP 1.2-/spl mu/m CMOS process and has an area of 2.35 mm by 1.97 mm including bonding pads. This 9-tap filter dissipates 70 mW when operating at 170 MHz. The multipliers are implemented using multiplying digital-to-analog converters (MDAC's) with 6-b resolution.
