  • Issue with Envelope analysis

    Hi, I am simulating the I/Q upconversion using port through envelope analysis. The I input pwl file has samples of a cosine of frequency=5MHz and timestep=0.00125us. The Q input pwl file has samples of value=0 and timestep=0.00125us. The original I, Q pwl files have data upto 2ms. I have attached the...

  • Re: VCO: PSS and pnoise analysis and Numerical Errors

    Hi Sivaramakrishna, If this is a strongly nonlinear circuit (e.g. ring oscillator), then pss-shooting is appropriate. Otherwise, I would use hb (harmonic balance). Please check out your setup - very important to get correct results. In my blog: SpectreRF Tutorials and Appnotes... Shhhh... We Have a NEW...

  • SpectreRF Tutorials and Appnotes... Shhhh... We Have a NEW Best Kept Secret!

    It's been a while since you've heard from me...it has been a busy year for sure. One of the reasons I've been so quiet is that I was part of a team working diligently on our latest best kept secret: The MMSIM 12.1.1/MMSIM 13.1 Documentation has been completely revised. It is a great source...

  • Re: What is the use of No of harmonics option in PSS form

    Hi yxue, In harmonic balance, the number of harmonics chosen does affect accuracy. There is a blog and a solution on this: Here is the Blog: Guidelines for Maximizing Speed vs Accuracy for Harmonic Balance - Part 2. http://www.cadence.com/Community/blogs/rf/archive/2011/11/01/guidelines-for-maximizing...

  • Modeling Oscillators with Arbitrary Phase Noise Profiles

    When you need to include noisy oscillators in SpectreRF transceiver simulations, you have at least 3 options: 1) Semi-autonomous simulation is the most accurate approach, recommended whenever the transistor-level model of the oscillator is available. 2) rfLib/osc model is less accurate but it’s...

  • Measuring 2-Tone Intermodulation Using Envelope-Following Analysis

    From time to time, SpectreRF users simulate very large, extracted-view circuits in 2+ tone QPSS. In many of those cases, memory requirements exceed the available resources. When that happens and small-signal approximations aren’t applicable, the user is typically stuck. The solution below and attached...
