John, Your schematic has the net "OUT" connected to the junction of R2 and C2. Move "OUT" to the output pin of U1. Mike

This circuit is basically an inverter with a bridged-T in the feedback. Since it has only one variable element, the amplitude of the peak and the BW (some say "Q") vary. Its usage is usually reserved

I would have, but I downloaded the article that triggered my interest it from Electronics Design News some months ago, and I can't now find it in the EDN articles. In the article is a reference to

Would you please supply the original article, chapter or whatever in which Bob Pease wrote his result? Thank you. DaveD KC0WJN [email protected]> wrote:

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
