This with the advances in VLSI (Very Large Scale Integration) technology, digital signal processing is penetrating into more and more applications. Many applications which have been implemented in analog domain have been moved to digital, such as wireless cellular phones. This paper presents a 16-bit Digital-to-Analog Converter (DAC) using 45 nanometer CMOS technology for mixed-signal applications. A segmented current steering architecture is used for this DAC in which 6-bits are used in thermometer coded architecture while 10-bits are used in binary weighted architecture. This architecture gives the most optimized results in terms of speed, resolution and power. The designed 16-bit DAC operates with two supply voltages, 1 V and 3.3 V.
