   Abstract : High-speed and high-resolution digital-to-analog converters (DACs) are vital components in all telecommunication systems. Radio-frequency digital-to-analog converter (RFDAC) provides high-speed and high-resolution conversion from digital domain to an analog signal. RFDACs can be employed in direct-conversion radio transmitter architectures. READ MORE

4. 2. Linear Interpolation D/A Converter Applied to Direct Digital RF Modulators

   Author : Zhou Yijun; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; Electrical engineering; SOC.; quadrature modulator; interpolation; filter; DSP; CMOS; DAC;

   Abstract : This thesis deals with techniques for the full integration of radio frequency (RF) transmitter with CMOS technology. The theory and implementation of high performance digital-to-analog converters (DACs) for radio frequency (RF) transmitters have been studied. A linear interpolation DAC architecture is proposed.
