中文摘要	a compact direct digital frequency synthesizer （ddfs） for system-on-chip implementation of the high precision rubidium atomic frequency standard is developed. for small chip size and low power consumption, the phase to sine mapping data is compressed using sine symmetry technique, sine-phase difference technique, quad line approximation technique,and quantization and error read only memory （qe-rom） technique. the rom size is reduced by 98% using these techniques. a compact ddfs chip with 32bit phase storage depth and a 10bit on-chip digital to analog converter has been successfully implemented using a standard 0.35μm cmos process. the core area of the ddfs is 1.6mm^2. it consumes 167mw at 3.3v,and its spurious free dynamic range is 61db.
