چکیده
This paper describes the concepts of Deltasigma converters and their increasing use with the development of fine line digital integrated circuit technology. Conventional Nyquist converters require analog components that are highly immune to interference and noise. On the other hand Delta sigma converters can be implemented by using simple and high-tolerance analog components. Sampling at high frequency in Delta sigma converters eliminates the need for abrupt cut-offs in the analog anti-aliasing filters. Noise shaping and over sampling technique is used in Delta sigma converters to achieve a high-resolution

متن کاملIP Generation for an FPGA-Based Audio DAC Sigma-Delta Converter
In this paper we describe a parameterizable FPGA-based implementation of a sigma-delta converter used in a 96kHz audio DAC. From specifications of the converter’s input bitwidth and data sampling frequency, VHDL generic parameters are used to automatically generate the required design. The resulting implementation is optimized to use the minimum internal wordlength and number of stages. We prot...
