Abstract :
A 0.25 /spl mu/m quadrature direct digital frequency synthesizer/mixer has 32b frequency control word, 0.07 Hz tuning resolution, 12b inputs and 13b outputs offering 90.3 dBc spurious-free dynamic range. The 4180 cell core occupies 0.36 mm/sup 2/. Power dissipation is <400 mW at 300 MHz.
