Implementation of 4-bit R-2R DAC on CADENCE Tools
An analog audio signal is continuously sampled; quantized and measured the height over time, and then the converted information is stored as series of numbers on the hard disk or in flash memory of an audio player. This series of numbers stored is known as digital audio signal. A compact disc(CD) stores these samples as 16-bit binary (1s and 0s) "words" 44K times a second, but digital audio data can be stored in a different sample rates, word sizes, and encoding or compression formats, and are brought to us on everything from our smartphone to your laptop. But in every case, the final thing that happens is the digital numbers get converted back into an analog electrical signal that can be sent to our headphones. The device that does this conversion is called a digital to analog converter (DAC).In this paper R-2R DAC converter is implemented on CADENCE tools with 180um technology.
