Design of decimation filter for novel Sigma-Delta modulator
Original language description
This paper describes steps involved in a new VHDL design of a decimation filter for a sigma-delta (Σ∆) modulator. Parameters of decimation filter are derived from the specifications of the overall Σ∆ modulator. Using Matlab and MathCAD tool it is possible to find the filter order, the required quantization level for the coefficients and their values. Finally, by analyzing the design, we can find an efficient way to implement the filter in hardware. This structure is designed in twoversions using VHDL. The first version is programmed and tested on a FPGA chip. Then second version was created for Cadence software tool to implement into a chip in the AMIS CMOS 0.7 ?m technology.

Návrh decimačního filtru pro novou architekturu modulátoru sigma-delta
Czech description
Tento článek popisuje kroky, které jsou nutné použít pro návrh decimačního filtru. Parametry decimačního filtru jsou odvozeny ze specifikace modulátoru sigma-delta. K návrhu decimačního filtru byly použity programy Matlab a MathCAD. Byly navrženy dvě verze decimačního filtru. První verze decimačního je určena pro programovatelné logické obvody a druhá verze je určena pro návrh na čip v technologii AMIS CMOS 0.7 ?m.
