  7. 20. Design Aspects of Fully Integrated Multiband Multistandard Front-End Receivers

    Författare :Adiseno; KTH; []
    Nyckelord :low-noise amplifier; mixer; RF front-end; wireless receiver; noise figure; linearity; bandwidth; dual-loop feedback;

    Sammanfattning : In this thesis, design aspects of fully integrated multibandmultistandard front-end receivers are investigated based onthree fundamental aspects: noise, linearity and operatingfrequency. System level studies were carried out to investigatethe effects of different modulation techniques, duplexing andmultiple access methods on the noise, linearity and selectivityperformance of the circuit.
