    DESIGN OF DECIMATION FILTER FOR MULTIBIT SIGMA-DELTA MODULATOR WITH TWO-STEP QUANTIZATION

  • Original language description

    This paper describes steps involved in a VHDL design of digital decimation filter for multibit sigma-delta (&#931;&#916;) modulator. Parameters of decimation filter are derived from the specification of the multibit &#931;&#8710; modulator with two-stepquantization architecture. Using Matlabtool it is possible to find the filter order, the required quantizationlevel 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 two versions using VHDL. The design is programmed and tested on a Xilinx FPGA -Spartan 3 XC3S200-5FT256.

    Návrh decimačního filtru pro vícebitový sigma-delta modulátor se dvěma kroky kvantovacího procesu.

  • Czech description

    Článek popisuje kroky při návrhu decimačního filtru v jazyce VHDL pro vícebitový sigma-delta modulátor. Parametry decimačního filtru jsou odvozeny ze specifikace vícebitového sigma-delta modulátoru se dvěma kroky kvantovacího procesu. Návrh decimačního filtru byl proveden teoreticky v programu Matlab. Výsledná implementace byla provedena v obvodu Xilinx FPGA Spartan 3 XC3S200-5FT256.
