Transient Assisted Harmonic Balance

Could you at least post the spectre log file and ideally the bottom part of the input.scs showing the options and analysis statements?

Andrew

Andrew, 

See below what I have attempted to do.  As I mentioned, I have a circulator with an RF input at Port 1.  I also have modulation frequencies with three different phases generated using a ring oscillator.  I am running the hb with the input frequency sweep and the oscillator, how can I plot the S-Parameters?

You didn't include the input.scs statements, and I was going to ask to see the hb set up but I see you've edited the post to show the hb form rather than the hbsp form.I could see from all the "semi-autonomous" messages in the log file that you must have both the oscillator and a large-signal input. Do you really need to have the RF frequency as a large signal? Normally you'd not measure the s-parameters with a large signal input unless you're trying to measure the s-parameters with the input driven into compression or a large-signal blocker present (for example). Having the large signal there complicates the hb analysis (although you said it wasn't converging - as far as I can see it's converged).

So what isn't working? There's no hbsp in the log file either.

Andrew. 

Andrew, 

Take it easy on me first time user.  Since I posted yesterday, I fixed the convergence issue. 

1. I am not sure what the input.scs is, how do I get that?  

2. I want to see the s-parameters so If i need to change the rf input and not have it as a large-signal, what steps do i need to get the s-parameters?  Do I change the port to dc and use hbsp?

Of course, but it does tend to help if you mention that you've solved part of your original problem! Otherwise I'm scratching my head wondering what your issue is - this is nothing to do with being new to the tool - it's just good practice when asking questions to let somebody know if part of your problem has been resolved.

Anyway some answers:

1. Use Simulation->Netlist->Display - this is the input.scs. You may not be able to share the entire netlist (as it's your design) but the piece at the bottom will help with the options and analysis statements.
2. Yes, I'd suggest you change the RF input port to be dc (or if it's a sine source set the frequency to be - maybe if it's a variable, you can change the variable value in ADE to be 0 instead).

Since you're using SPECTRE17.1, you can look at the database in your SPECTRE installation:

<SPECTREinstDir>/tools/spectre/examples/SpectreRF_workshop/rfworkshop.tar.Z

unpack this somewhere using "tar xvfz rfworkshop.tar.Z". Underneath the "doc" directory there are several pdf documents, including one for Mixers - that has an example (based on the database provided) that shows how to set up hbsp.

In general you need to define the physical port and the frequency (i.e. the harmonic) of the port - then you are producing the s-parameters between these "virtual ports" that you've set up on the form. What this should be set to rather depends on what makes sense for your circuit.

Regards,

Andrew

Andrew, 

Thanks for all your help.  This is where I am at now.  I setup a Transient Assisted HB wtih two tones, one is the local oscillator and one is the RF input at Port 1.  I then setup a hbsp to calculate the SP at the RF input so it is a single point and not a sweep.  I am sweeping using the parametric tab in orber to run the oscillator for every RF frequency input.  I am attaching both the input.scs and the output log of this analysis. 

From the HB i see the spectrum and the mixing but I am not getting any SP plots from hbsp.

You're still running semi-autonomous harmonic balance (i.e. you still have the large signal RF input enabled). Why is that? I suggested you probably don't want to do that. Also, you have your hbsp to be just a single point (so maybe that is confusing you?) rather than a sweep. More importantly, you have the frequency of the ports set to 3GHz, which is exactly the same frequency as the large signal input. So that means you have a large-signal input (in the hb) at 3GHz and a small-signal input (from the hbsp) on the same port at the same frequency - that's why there's a note in the spectre log telling you that the results might be inaccurate.

You've also (by the port harmonics you've specified) given the input and output frequencies as 3GHz, did you mean that? (you may have done - not quite sure what you're trying to measure).

With the simulation you had. I get waveforms for the s-parameters with only a single point at 3GHz, and the results are rather confusing given that you have a large signal and small signal at the same frequency. So I changed Frf to 0, and ran a single tone hb and set up the hbsp to sweep from 3G to 3.2G (just for interest), keeping the relative port harmonics as 0 (so no frequency shift) and then you get:

Perhaps that's what you're expecting?

Andrew, 

I mentioned in my original note, that I was sweeping the frequency using parametric sweep and that's why my hbsp had only single point.  I am sweeping from 2.2G to 3G.  I did this because  I wanted to run the transient for every frequency input to get the mixing between the RF and the locally generated modulation signal(from the oscillator). 

If I change Frf=0 then HB simulator will only have 1 tone Correct?  Also another question, when you run hbsp, does take into account the transient analysis done in HB before hand and applies that to every frequency point? 

I don't think this makes sense. Doing the sweep in the hbsp is more meaningful I think (and considerably more efficient). Note that with just the oscillator enabled is indeed performing a single tone harmonic balance, but the hbsp analysis will then be performing a two tone analysis - it's just that the second (RF) tone only computes the linear terms of the mixing products with harmonics of the oscillator frequency. Given that s-parameters are a linear representation, that should be sufficient.

As I said, the only reason for having the RF frequency present in the harmonic balance analysis itself is if you want to compute the s-parameters in the presence of a large signal blocker; note that the this would mean that the hbsp is effectively applying a second RF input frequency (which is treated linearly) and would mix with harmonics of both the oscillator and the large-signal blocker. That's why numerically it doesn't make sense to apply it at the same frequency as the large signal input - you can't really distinguish between the small signal applied on top of the large signal.

I don't really understand why you want to "run the transient for every frequency input". You don't need to do that to compute harmonic balance responses anyway. The transient is only there to assist the convergence of the frequency domain solution by giving it a starting point closer to the final solution. In fact with a semi-autonomous (or indeed any multitone harmonic balance), the transient assist (tstab) part only has the first tone (the oscillator in this case) enabled because otherwise it would lead to the need to simulate the tstab over multiple periods of the common frequency of all tones - which with a free-running oscillator present could be a very long time indeed.

Andrew.
