Abstract
The area and power consumption of oversampled data converters are governed largely by the associated digital decimation and interpolation filters. This paper presents an area- and power-efficient programmable digital filter for decimation and interpolation in digital-audio applications. Several architectural and implementation features reduce the complexity of the filter and allow its implementation in a die area of only 3670 mils/sup 2/ (2.37 mm/sup 2/). The filter is first described in the context of decimation for an oversampled A/D converter employing a second-order sigma-delta modulator. Extensions of the filter to accommodate other modulators, as well as to perform interpolation for oversampled D/A conversion, are then discussed.
