| 英文摘要 | This paper presents a direct digital frequency synthesizer (ddfs) with a 16-bit accumulator, a fourth-order phase domain single-stage delta sigma interpolator, and a 300-ms/s 12-bit current-steering dac based on the q(2) random walk switching scheme. the delta sigma interpolator is used to reduce the phase truncation error and the rom size. the implemented fourth-order single-stage delta sigma noise shaper reduces the effective phase bits by four and reduces the rom size by 16 times. the ddfs prototype is fabricated in a 0.35-mu m cmos technology with active area of 1.11 mm(2) including a 12-bit dac. the measured ddfs spurious-free dynamic range (sfdr) is greater than 78 db using a reduced rom with 8-bit phase, 12-bit amplitude resolution and a size of 0.09 mm(2). the total power consumption of the ddfs is 200)mw with a 3.3-v power supply. |
