| 中文摘要 | this paper presents a direct digital frequency synthesizer (ddfs) with a 16-bit accumulator, a 4th-order single-stage pipelined delta-sigma interpolator and a 300ms/s 12-bit current-steering dac based on q(2) random walk switching scheme. the delta-sigma interpolator is used to reduce the phase truncation error and the rom size. the measured spurious-free dynamic range (sfdr) is greater than 80 db for 8-bit phase value and 12-bit sine-amplitude output. the ddfs prototype is fabricated in a 0.35um cmos technology with core area of 1.11mm(2). |
