Digital to analog converter design assessments using a current source architecture

A current source digital to analog converter is inherently fast. It can be implemented in most semiconductor technologies. This post and its accompanying article/ white paper describes one such DAC that uses a 0.18um CMOS technology ( decidedly legacy in semiconductor terms) but its assessments are equally applicable to latest CMOS technology. The various analysis for circuit, performance, power etc. etc can be used as a template with appropriate modifications for any CMOS process. Please visit the Signal Processing Group Inc., website to access the full white paper that can be found under the “complementary” menu.
