Direct Digital Frequency Synthesizers implemented on high end FPGA devices
Mariangela Genovese, Ettore Napoli · 2013
Direct Digital Frequency Synthesizer (DDFS) circuits are routinely implemented in many electronic systems. Advanced DDFS design techniques have been proposed and optimized for ASIC (Application Specific Integrated Circuits) implementations. Nowadays, FPGA devices are frequently chosen as target for digital circuits. This paper presents the FPGA implementation of state of the art DDFS architectures and compares their performance providing hints on optimal design as a function of the chosen performance parameter.
