Abstract :
A 10b 600MS/s current-steering DAC, implemented in a 65nm CMOS process, realizes direct waveform synthesis for TV band cognitive radio applications. A multi-mode reconstruction technique enables the DAC to utilize the image spectrum in higher Nyquist zones for wideband direct synthesis. The measured SFDR is better than 55dB across the first three Nyquist zones at 600MS/s with 30mW of power dissipation.
