Abstract :
A direct digital frequency synthesizer/mixer IC processes two 12b quadrature inputs by providing two quadrature 13b outputs with a SFDR greater than 90dB and a frequency resolution of 0.088Hz at 380MHz clock frequency. The IC has an area of 0.22mm2 in 0.25mum CMOS and dissipates 150mW at 380MHz with a supply of 2.5V. At 1.8V, the power dissipation is 53mW at 270MHz
