Abstract :
This paper discusses a number of circuit approaches which address lowering the power consumed by a modern current steering DAC while maintaining both DC and AC performance levels. An example design provides 14 bit resolution and 250 MSPS conversion rate in a 1P4M 0.18mum CMOS process, with optional 3.3 volt compatible devices. A power dissipation/conversion rate figure of merit of as low as 0.17 mW/MSPS was achieved for 1.8V operation and as low as 0.28 mW/MSPS at 3.3V. SFDR of 70 dB is achieved at a 50 MHz output frequency
