High-resolution low-power CMOS D/A converter

Abstract
A very low-power, high-resolution, medium-speed D/A (digital-to-analog) converter is described. The converter was realized using a standard analog CMOS technology. It achieved 15 bits monotonicity and less than 0.7% overall linearity at a clock frequency of 100 kHz, without requiring any trimming or calibration. The measured SNR (signal-to-noise ratio) was 85 dB, and the measured power dissipation was less than 10 mW.
