High-speed direct digital frequency synthesizers (DDFS) were designed in silicon-on-insulator (SOI) CMOS technology for space applications. The DDFSs were designed using two approaches. One approach used a standard binary digital-to-analog converter (DAC) and algorithms to minimize power dissipation and the amount of ROM look-up table required. The second approach used a non-linear DAC, which required only a small look-up table. Results of simulations showed operating frequencies of 2 GSps for both DDFSs with a DAC resolution of 12 bits.
