  • Abstract
    The paper presents a novel architecture for a direct digital frequency synthesizer (DDFS) based on the quasi-linear interpolation (QLIP) method. The four-segment QLIP is utilized to realize a DDFS with a spurious free dynamic range (SFDR) of 63.2dBc. The DDFS chip featuring a 5-stage pipeline is implemented in TSMC 0.13mum technology. The chip occupies 9874mum2 , consumes 8.2muW/MHz, and runs at 1GHz clock rate.
