Field Programmable Gate Array Implementation of 14 bit Sigma-Delta Analog to Digital Converter

This paper the design and FPGA implementation of a delta sigma A/D convertor. The proposed converter has been designed using Xilinx system generator tool, which reduces the design cycle by directly generating efficient VHDL code. The VHDL code has been implemented on a Spartan 3E xc3s100e-4vq100 FPGA using ISE 12.4 tool.
