  4. 18. Design and Implementation of Common Drain Class-B RF Power Amplifier in 90 nm CMOS Technology

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Muhammad Abdullah Khan; [2011]
    Keywords : ;

    Abstract : Power Amplifer (PA), is a key component in a wireless communication system. It is challanging to design a PA having sucient gain, linearity and eciency all at the same time. Linearity is important to avoid interference among the channels while high effciency corresponds to longer battery life. Gain is important to reduce multiple stages. READ MORE
