DESIGN AND IMPLEMENTATION OF HIGH-SPEED 4-BIT R2R DAC

With the rapid development of modern communication and personal wireless products, there are increased demands for next generation communication transceivers that feature ultrahigh data conversion rates with reconfigurable architectures. As the essential building block in most communication and control system are data converters, including analog-to-digital converter (ADC) and digital-to-analog converter (DAC), they are serving as the link between analog and digital world. In this project, Digital to Analog Converter (DAC) is designed which facing high-performance demand in high-speed and high-resolution signal processing, telecommunication and data converter applications. Here, presenting a 4-bit R2R DAC simulated in LT spice software.
