Abstract :
A single-chip direct digital frequency synthesizer with hardware efficient phase-to-amplitude mapping and an integrated DAC achieves over 50dB SFDR in full-Nyquist band at 1.7GHz clock frequency for synthesized output signals up to 850MHz. The IC is implemented in a 0.35 μm SiGe BiCMOS process and occupies an area of 4.8×5.0mm2. Power efficiency is 1.76mW/MHz at 3V.
