Delta-Sigma Modulation for Direct Digital Frequency Synthesis
2009
IEEE Transactions on Very Large Scale Integration (vlsi) Systems
This paper compares different 16 modulation techniques for direct digital frequency synthesis (DDS). 16 modulators such as MASH, feedforward, feedback, and error feedback have been implemented in both the phase and frequency domains in a CMOS DDS prototype IC fabricated in a 0.35-m CMOS technology with core area of 1 7 2 1 mm 2 and total current consumption of 75 mA. Measured DDS performance demonstrates that the frequency domain 16 modulation technique achieves better output spectrum purity
