Multi-bit oversampled ΣΔ A/D converters as front-end for CD-players

A technique is presented to derive all the control signals needed for focusing and radial tracking in a digital servo system for CD-players, as well as the full-band data, with multi-bit ΣΔ A/D converters. The ΣΔ approach is of great interest because of its suitability to integrate in a VLSI process...
