    Re: Help ??? Some ideas for PA and LNA design

    You'd better read the cllassic book about PA and PNA and design a PA or LNA. It doesn't matter if it works well. "RF Power Amplifiers for Wireless Communications" is recommended as a classic book about PA.

    Re: Help ??? Some ideas for PA and LNA design

    also u need to know the new trends in this filed also

    in LNA , the multi standard LNA is a very hot topic , and also a wide band LNA

    about PA , the switching classes are great , and the linearziation techniques also have a great research

    Re: Help ??? Some ideas for PA and LNA design

    the switching classes of the power amplifier , the active element "mos, bjt , HEMT" used as a switch to on and of

    like classe E , D power amplfiers

    they are a nonlinear classes , and need linearization techniquies

    Re: Help ??? Some ideas for PA and LNA design

    noise cancellation , simply u put a MOS device so it is noise current cancels out some of the noise in the ouput of the amp to achieve less noise figure , but i have no more detail , i heard about it , but u can check in the IEEE , u will find alot

    Re: Help ??? Some ideas for PA and LNA design

    Hi,
    I don't think you can speak about a trend, instead i will be better to identify an application and then choose the kind of amplifier you wil develop.
    if you are interested in RFIC I think there are a lot of example and choices in wireles market...GSM, WiMax....
    Then I think you need an idea about the process you can have access and the pdk you can use...

    Bye.

    Re: Help ??? Some ideas for PA and LNA design

    i think he mean by process idea , some knowledge about the process u will use to design LNA and PA , like what is the mnimum channel length , number of metal layers , are there inductors , and so on

    Re: Help ??? Some ideas for PA and LNA design

    Hi Khouly

    Are you working on distributed amplifier ? can you give me some ads-example? and what about the Rf tsmc 0.18µ design kits ? do you want to send it for me?
    thanks a lot
