Analysis and comparison of Direct Digital Frequency Synthesizers implemented on FPGA
The best performing DDFS architectures proposed to date are implemented on FPGA devices. State of the art DDFS circuits are optimized to better suit the FPGA technology. Implemented DDFS is compared against the IP of the FPGA manufacturers. ROM based architectures are the best performing ones for low SFDR values. For higher SFDR values more advanced architectures are required.
