A direct digital frequency synthesizer with fourth-order phase domain ΔΣ noise shaper and 12-bit current-steering DAC.
This paper presents a direct digital frequency synthesizer (DDFS) with a 16-bit accumulator, a fourth-order phase domain single-stage ΔΣ interpolator, and a 300-MS/s 12-bit current-steering DAC based on the Q2 Random Walk switching scheme. The ΔΣ interpolator is used to reduce the phase truncation e...
