High Performance Digital to Analog Converter Using CMOS 45nm Technology

This article represents about 8-bit digital to analog converter (DAC). A digital to analog converter (DAC) takes a digital signal and converts it to an analog signal (i.e; continuous form) to drive the interfaces with the real-world such as a speaker in the cell phone or the LED display on your watch. As such, anytime a digital circuit has to interface to a display or a speaker or an antenna or any number of other devices that need to be driven by an analog input and required a digital to analog converter (DAC). Digital to analog converter (DAC) is more efficient and substantially more accurate to do signal processing in the digital domain (i.e language used by computers). This article represents a digital to analog converter (DAC). The DAC was implemented by using 45nm CMOS technology. It also consumes 1.46mW of power from 1.8v supply voltage. The noise margin of the DAC is 9dB.
