Abstract

A design technique is described for the realization of a digital-to-analog (D/A) conversion system with an embedded finite impulse response (FIR) filtering function suitable for the compensation of the sin x/x distortion introduced by fully sampled-and-held signals and which is attractive for integrated circuit implementation from the viewpoints of area and power consumption. This is demonstrated for an 8-b D/A conversion prototype system with an associated 3-tap 5-b precision FIR filtering function that has been fabricated using a 1.2-μm digital CMOS technology
