Abstract :
This paper presents a sigma-delta audio digital-to-analog converter (DAC) implemented on a single field programmable gate array (FPGA) for non-commercial application. The simulations´ results of the digital interpolation filter and digital sigma-delta modulator are shown. The results of an FPGA-based hardware implementation will be obtained and presented soon.
