    [SOLVED] Cadence Virtuoso and MMSIM installation

    I got same ERROR (ADE-3036), but I have solved this by 1) install libreadline5 2) go to ADE-->Setup-->Environment Options, thick "Run With 64 bit binary" option

    varactor diode model in Vco design

    varactor vco Hi IKUZU please refer this link regarding varactor diode model in Vco design, althought it was related ADS but I believe it could be applied to AWR as well due to generic varactor lumped model

    problem with orcad 9.2

    error_ _is less then 2 connection From my point of view, the simulation is correct, I guess your question was wondering the 4.1 mVDC product at output, it was due to one of OPA's characteristic, input offset voltage.

    problem with orcad 9.2

    less than 2 connections at node pspice that is because the U1 you chose was not a pspice model, it is just a symbol for schemadic drawing. you should choose pspice model in \capture\library\pspice

    problem with orcad 9.2

    pspice less than 2 connections at node that is because you didn't make R1,R2 and U1 connecting properly by wire. suggest you moving them away each others and re-connecting exactly at pin point.

    how to simulate the varactor c-v curve

    simulate varactor c-v I did that before by using ADS, but you need a non-linear varactor model first. you can search this board to get informations how to get a non-linear model if you don't have.

    help! targets in designing amplifier with @DS!

    Basically You can't do DC simulation if you only got S-parameters data, you need a non-linear or spice model.

    What are the criteria of selecting frequency for RFID?

    Re: Question about RFID. everything is possible if you have theory standing for, but why not using Thermo Life to get electricity energy instead of radio signal energy?

    [Help]Extract S-Parameters: High Power Microwave Transistor

    Re: [Help]Extract S-Parameters: High Power Microwave Transis I used HP 8753D to finish that job for my last project, I don't know which is best but I do know it should be calibrated properly before starting measurement. btw, the S-Parameters you got by this method are just what transistor...

    [Help]Extract S-Parameters: High Power Microwave Transistor

    Re: [Help]Extract S-Parameters: High Power Microwave Transis you could try my method as shown in the attachment. 1. put DUT into 50 ohm transmission lines test fiture board and add feedback network if necessary. 2. tune and move both Cin and Cout until meet requirements 3. take off DUT, measure...
