  5. 4. On High-Speed Digital-to-Analog Converters and Semi-Digital FIR Filters

    Författare :Mohammad Reza Sadeghifar; J Jacob Wikner; Robert Hägglund; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DAC; RFDAC; SDFIR; FIR; semi-digital FIR filter; digital-to-analog converter; D A converter; data converter; mixed-signal integrated circuits; mixer DAC; IQ modulator; transmitter;

    Sammanfattning : 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. LÄS MER
