WebDDFS – An Overview Direct digital frequency synthesis (DDFS) is a method of producing an analog waveform—usually a sine wave— by generating a time-varying signal in digital … Webimproved. The proposed DDFS is implemented in a standard 0.13 µm cell-based technology. The maximum clock rate is 227 MHz, and the core area is 0.25 mm2. The simulation result shows that the spurious free dynamic range (SFDR) is 117 dBc. I. INTRODUCTION Frequency synthesizer is an essential part for communica-tion systems.
WebNov 22, 2016 · A DDFS is designed and fabricated using the 0.25 μm SiGe HBT process and achieve a maximum operating frequency of 4 GHz. The measurement shows the prototype DDFSs produce a minimum spurious free dynamic range (SFDR) of 46 dBc from dc up to Nyquist frequency when clocked at 4.0 GHz. This paper is arranged as follows.
