I have uploaded the above as a .ZIP. According to Bob Pease, the gain at the peak should be close to 34 dB, independent of the tuned frequency. I don't get either of those results using version

@Andy In this case, shall I use the Figure 1 crystal model inside the IEEE paper ( http://ieeexplore.ieee.org/document/318/ ) or https://en.wikipedia.org/wiki/Van_der_Pol_oscillator ?

Hi Dan, IMD testing in RF can be done with two tone testing and looking at the spectrum of the output or you can use a single input, step its value and plot gain against the power out. In a well

Hi Andy, Thank you so much for your explanation. It was very helpful! I just have one more question (I hope I’m not bothering you): in our example, the power supply voltage is 5V. But what if our

No John. Just one of likely numerous ways.

This gentleman does a nice review of your query. See page starting at 16... https://www.gunthard-kraus.de/LTSwitcherCAD/SwitcherCAD-Tutorial_English/pdf-File/RF_English_01_final.pdf

I think such a feature would be very useful. I've made a feature request to ADI.

Tony thanks, I've downgraded to 24.0.9 I've found on my disk. The Bordodynov lib (I've been using various exotic parts from) needs a deep cleanup with the latest, otherwise it does not allow to start

Plain old common sense (which might not be correct) suggests that you would want to use a .FOUR command to extract the amplitudes, and then use it with time-domain (.TRAN) simulations where you .STEP

Note that LTspice can export (convert) the schematic into netlist files for a variety of CAD programs.? In the schematic viewer, go to Tools > Export Netlist, and read the Help page for Schematic

Thank you for uploading the schematic. I don't know exactly what was the "distortion" you saw.? There are spikes on the waveforms at either end of the resistor.? Those spikes mostly disappear when

You should search the group archives yourself first. Those are the files with 'z-xxx' names on the Files web page. Also, look in the Examples that come with the app, and the Wiki. -- This email has

Are there any files, messages etc, that detail how to plot the IP3 of an rf amplifier using LTspice?? I would be interested in comments and examples on this subject.

The devs would probably argue that your libraries haven't been corrupted, but always failed "correct" syntax previously. Anyhow, this has already been discussed here at length, and there has been a

Many things are possible. Default parameter values for LTspice, at least, are listed in the Help, so you could create your own default intrinsic models if you wished - put them into the standard.xxx

.. LTspice checks the complete lib files in use for the proper syntax, line by line (a good move basically)..

I am not sure whether some of my libs got corrupted, but with the latest LTspice release and its stronger syntax check ie. the Bordodynov lib shoots huge number of errors which must be corrected

Inside each .model there will definitely be default values stored somewhere, which could be returned if one is not provided explicitly in the .model statement, so I don't see why this couldn't be
