Abstract :
A low-voltage low-power small area digital-to-analog (DAC) for mixed-signal applications is introduced. A full equally weighted current steering DAC is a performance-efficient architecture for 8-bit resolution, due to almost all the current taken from the supply is used for the output signal. The current steering architecture is also highly suitable for high-speed operation and requires no calibration, trimming, or dynamic averaging. The circuit operates from a 2-V power supply in a standard 0.25 um CMOS technology. The measured DNL/INL is 0.23/0.3, and output 200-kHz signal achieves 50 dBc SFDR at 10 MS/s update rate with power dissipation of 2 mW.
