Design of an Optimized CMOS Thermometric Type Digital to Analog Converter

Abstract This paper explicates the design of thermometric type of digital to analog converter for the data communication applications which require large accuracy and full scale output voltage evaluated is 1.4 V along with very less power consumption of 2.4mW. Implementation of data converter is achieved with thermometric type of digital to analog converter and layout is realized in 180nm technology. A 4 to 15 decoder is designed which transform the binary to thermometric required for architecture of thermometric current steering digital to analog converter.
