A Survey: R-2R Digital to Analog Converter Implementation Using Cadence EDA Tool
Abstract
An option in contrast to the binary weighted-input DAC is the supposed R/2R DAC, which utilizes less special resistor esteems. A disservice oftheA digital-to-analog converter which depends on the R-2R stepping stool is investigated for low power utilization i.e.27.04 mW, low dynamic chip territory for example 0.054 mm2 and low DNL for example 0.03. R-2R DAC is executed utilizing rhythm virtuoso device in 180nm CMOS process. The main components used are an operational amplifier and R-2R ladder network. Op-amp is made up of two stages. The first stage of op-amp consists of a differential amplifier and the second stage consists of common source amplifier. The first stage is used to get high gain and the second stage increases output swing and gain of the first stage.
