  • PA constant efficiency contours
    Hi, I am trying to do a load-pull simulation to study the optimal load condition for a CMOS Power Amplifier. For this, I use the parametric PSS simulation with a portAdapter to traverse all possible reflection coefficients (gamma) on the smith chart. After the simulation, I use the 'Power Contours' option in the Direct-Plot form to plot ...

  • Error in HB analysis Setup
    Hi, I am using Cadence Spectre (Version : IC6.1.3.500.13). I am working through the examples in the SpectreRF_Workshop available at  <mmsim>/tools/spectre/examples/SpectreRF_Workshop  All the Labs have 2 ADE sessions, one using PSS and the other HB. The PSS based simulations work fine but when I run HB analysis, I keep getting ...

  • Re: Using ADE calculator with SP Analysis
     I figured out how to print the data into ocean for post processing in a earlier post on this forum  http://www.cadence.com/community/forums/T/10561.aspx  Any inputs on using the calculator for this would be welcome though!  cheers! Venu

  • Using ADE calculator with SP Analysis
    Hi, Could I get some inputs on how to use the result of the s-parameter analysis in Spectre to do post processing in either WaveScan or AWD? I need to use the s-paramter or y-parameter data to compute this large expression {I Y12 - Y21 | ^2}   /  {4*{(Re(Y11)*Re(Y22) - Re(Y12)*Re(Y21)}} If computing this in Spectre is not easy, Is ...

  • Re: SP-Simulation : GPC Option
    Hi Tawna, Thanks a ton! Great pointers. At the University we have a complete Cadence Installation, could you tell me where I can find the schematic for the differential amplifier described that LNA design spectre RF note (LNA_62_appnote). In case it comes with the installation, there must be some standard path I can search It is not present in ...

  • SP-Simulation : GPC Option
    I have a question about how to interpret the power gain circles plotted using Spectre's SP analysis For plotting the power gain circles on the Z-smith chart , there are 2 options: Frequency and Gain Level  Suppose I select sweep  "Gain level"  Start = 5dB , Stop = 20dB , step = 5 In my circuit, input port = ...
