    Cadence Spectre error message for TSMC MM 0.18 PDK

    Answer by myself :D cd your_INSTALL_DIR/tools/dfII mkdir local cp your_INSTALL_DIR/tools/dfII/samples/local/cdsinit your_INSTALL_DIR/tools/dfII/local/.cdsinit That's ok...

    Hi , about impedace matching

    Find the input impedence of Ant sw. If it is not available in datasheet, you can measure the s11 of Ant sw input by network analyzer. Then just match it to 50 ohm(if it is PA output impedence)

    LNA power gain in RFIC 0.18um processor

    Because the LC tank parallel resistance in resonant frequency is propotional to Q value of inductor.

    A simple question about PA selection.

    Sure! But in personal communication system or portable device which concerned about battery lifetime will take much attention in power saving.

    LNA power gain in RFIC 0.18um processor

    Select a loading inductor with a higher Q value can improve power gain. Or use cascode type to increase isolation. Last, increase current also can improve some performance

    A simple question about PA selection.

    PA for WLAN need a lot of power backoff. Because the modulation type is QPSK for 11b and 64QAM for 11g at maximum data transfer rate. In these modulation, the linearity of front-end circuit is more important. Therefore, the backoff is needed. So it would cost much current consumption in this...

    RF book or RF E-book for engineer (English version)

    Thanks very much to BigBoss I can get it now. What is "PM" meaning? Because I wanna know more information about cmos LNA and Power amplifier for wirelessLAN. Regards
