    CMOS inductor with different substrate resistivity

    cmos inductor hello, everyone. now i have a EM-simulation question about CMOS inductor with different substrate resistivity the inductor layouts (N=4.5, W=10um, S=2um and Rin=60um) and process parameters are same and the substrate resistivity is 1000, 100, 10, 1, 0.1 respectively, the unit is...

    Should I choose which type of mixer?

    the first specification is reasonable, and u should choose the gilbert cell for the isolation required.

    question on input power in PA

    so how can i get a variable gain in PA, couple a power detector at the output port of the power stage of PA and feed back to the input port of the drive stage of PA, and when the output power is more or less than 28dBm, then make the input power decrease or increase ?!

    Should the two ground pins of GSG pads be connected together on chip?

    gsg layout i think you can connect the two ground pins together using some metal lines, but if you don't do this, that's no problem. practically when you test your devices or circuits, the two ground pins of the G-S-G pad would be contacted to the two ground terminals of the probe...

    question on input power in PA

    in cdma pa design, the input power is not constant when the output power is fixed (e.g. 28dBm). the input power generally vary from several -dBm to several +dBm. so the question is how to make a stable output power when the input power is varied. anybody know some solutions? thanks a...

    Quiescent Current in RF PA

    Thanks. but how can i get the quiescent current in a simulator, e.g. in @DS. and, if no input signal, that is like dc simulation. however, DC simulation is indepedent with max output power or modulation. expect an explanation.

    Quiescent Current in RF PA

    what is the quiescent current in PA? somebody told me that is the dc collector current value, right? thanks.

    Ruggedness No demage in PA design

    ruggedness pa hello, every1. in pa design, one of specifications is ruggedness no demage, the typical value is 10:1 & the unit is VSWR, but what meaning the "ruggedness no demage" is ? anybody can explain it for me thanks a lot.

    What is the s parameter in BJT model in @ds?

    about a BJT model in @ds I had downed a @ds model on a BJT with its s parameter data file from @gilent web site. However, i don't know the s parameter derivated of the DIE model(bond pad capacitance included) or the SOT-143 plastic model. who can help me? thanks
