Design and implementation of video DAC in 0.13μm CMOS technology

This paper presents the design and implementation of video digital-to-analog converter (DAC) in CMOS 0.13μm technology on 8 bits resolution, 500 MS/s, with good performances, smaller area, low glitch energy, which makes it suitable for RAMDAC (Random Memory Access Digital to Analog Converter) application. The proposed current steering DAC is a fully thermometer architecture which assumes a smaller area for a single DAC unit with a new deglitching circuit architecture added to improve the dynamic performances. In this way the interface between the digital part, which operates at low power supply 1.2V, and the analog part operating at 3.3V supply is made possible.
