PASSIVE MIXER DESIGN

RFstudent

Hi,

I am starting out on doing simulations on cadence. I have materials to simulate an active mixer design, but there are none for passive. How do i start out, if i want to design a double balanced passive mixer?

Thanks

    You might consider the following:

    K. Komoni and S. Sonkusale, "Modeling, simulation and implementation of a passive mixer in 130nm CMOS technology and scaling issues for future technologies," 2008 51st Midwest Symposium on Circuits and Systems, Knoxville, TN, USA, 2008, pp. 410-413, doi: 10.1109/MWSCAS.2008.4616823.

    Hi,

    Thank you so much. While the theory makes sense, I dont quite understand how to start with the simulation. How to perform dc and sp operations and how to ensure that the quad fet ring is infact being switched. Could you please attach a reference manual/materials, if any, it would be of great help!

    Thanks

    There are a variety of common RF setups described in this Article on COS. SpectreRF Application Notes and Tutorials - One of our best kept secrets!    See

    RF Documentation Workshop and Database:

    • ​Workshop database is located here: <SPECTRE21.1>/tools.lnx86/spectre/examples/Legacy/RF_Doc_Database.tar.gz

    It has a Mixer example which should get you started in ADE Explorer.  It doesn't cover your exact example.  For that, I recommend filing a Case on https://support.cadence.com .

    best regards,
