    Typical integrated L and C values at 10 GHz in parallel LC oscillator

    Dear edaboard community, I would like to ask you what is the typical integrated L and C values at 10 GHz resonance frequency in a parallel LC oscillator. Here is the topology that I am going to use, Thank you very much. Kind regards, Pablo Marco

    A question about "the negative resistance of cross-coupled pair"

    But this is for the case when we have a parallel LC tank oscillator, right?

    A question about "the negative resistance of cross-coupled pair"

    Yes thank you for your reply, it was what I have been doing. I just realized that I have been missing a point. I would like to share the solution for the community's disposal. Best regards, Pablo Marco

    A question about "the negative resistance of cross-coupled pair"

    I have seen these videos, but they are not related to my issue because in my question I am trying to find the impedance seen through the source, In the videos, the impedance seen through the drain is studied. Thank you for your response. So I am still looking for help for deriving it.

    A question about "the negative resistance of cross-coupled pair"

    Dear edaboard community, I would like to ask you a question about the following figure. Could you please help me derive the impedance seen through the source terminal of the pair? I wanted to derive it by myself (using the small signal model), but I could not achieve a result. The result is...

    A QUESTION ABOUT THE SMALL SIGNAL MODEL OF THE IMPROVED WILSON CURRENT MIRROR

    Hi everyone again and sorry for bothering you. I still could not answer my question by myself so I would like to try my chance again to get an answer from the community :) Thank you for your time. Kind regards, Pablo Marco

    A QUESTION ABOUT THE SMALL SIGNAL MODEL OF THE IMPROVED WILSON CURRENT MIRROR

    Hi everyone, I would like to ask a question about the small-signal model of the Improved Wilson Current mirror. First of all, RL represents the resistance that is seen when we look up through the drain of M4. I am confused about the G3 node because as can be seen in the small-signal...

    Magnitude and Phase Measurement of a Differential-out Ota in Cadence

    Hi, I am an engineering student. I need to measure my OTA's open-loop magnitude and phase plot in Cadence. Since I am going to design a differential-output OTA, I am quite confused about how I should implement a testbench for that purpose. I would be pretty happy If you guide me. Thanks in advance.
