Delta-sigma oversampled systems, particularly A/D converters are very useful circuits. This is specially true now when the semiconductor line widths are decreasing significantly and purely analog converters are becoming hard to design and implement in VLSI technology. A delta - sigma converter is mostly digital with a small amount of analog circuitry. As fine line technology is well suited to digital implementation a delta - sigma converter can be very useful indeed. A brief paper on the delta-signal principle was released by Signal Processing Group Inc. and may be found under the free reports accessed by registering on the SPG website by interested readers.
