I have mostly needed to be away from my computer all day today, so I did not yet actually try simulating your circuit.? I only saw that the pieces were there. Andy

Yes, correct. You have not been banned, so you can still ask for help. But I give you another tip - in future use more explicit subjects than 'test'. Everyone and his cat has a file called 'test'. I

I’m sorry. I count one email with a definitely wrong subject: RE: [LTspice] Model of BF970 The others have different subject files which I have emailed, but they are each my own: test.asc test.asc

No, you didn't correct it. You continued the same thread, but with a different subject. By "start a new topic", I mean you start a new email thread by either: 1. Clicking "New Topic", if you're using

Yes, I noticed this and apologized for and corrected it in subsequent posts. Regards, Chris Sent: Sunday, March 30, 2025 1:24 PM To: [email protected] Subject: Re: [LTspice] test.asc Can you please

Can you please not hijack a thread. Start a new topic. What you did was reply to a message in the "Model of BF970 ?" thread, and simply change the subject. This is very irritating for anyone that uses

Andy, I apologize for the cockpit errors. Subject file has been uploaded. At the top of the test.asc file, I noted that I’m using an old LTspice : 17.1.14 - Chris Sent: Sunday, March 30, 2025 11:55

You uploaded the symbol for ADA4098-2 by accident.? It's not the same shape and has an extra pin. Yes, it is indeed there in newer versions of LTspice 24 (v24.1).? But not in older versions. Andy

Hi Andy, I note your concern about my use of opamp possibly causing conversion problems. But it’s opamp that inexplicably works! It’s the ADA4084-2 which has conversion problems. Regards, Chris

Hi Andy, I added the 1N4007 as a .model statement on the schematic. The LM317 and the ADA4084-2 are in the . ADA4084-2.zip along with the updated test.asc file. Strangely, in my LTspice, the ADA4084-2

Another stupid mistake on my part.? I wrote: I had the polarity wrong when I looked at V6.? Never mind! Andy

I wrote: Oops.? I meant " *convergence* problems".

I don't know if this matters - but it looks like you run the ADA4084 with inputs BEYOND the power supplies.? Its datasheet claims RRIO, but not beyond-RRIO.? Can it work that way? Its datasheet says

Can you please include the missing LTspice symbols and SPICE models?? We can't help you without them. LM317A_TRANS ADA4084-2 (The latter might be in newer LTspice versions, but the computer I am

I never pretend or intend for someone else to do the hard work. That is for me to try, because that way I learn. What I did need help on that thread was with adding a HP filter for a specific very low

That is not quite true. The Laplace version has the disadvantage that the Laplace transform from frequency domain to time domain sometimes does not produce the right result - but sometimes it does,

Apologize for the wrong email heading you just received. This is the corrected one. Sent: Sunday, March 30, 2025 9:00 AM To: [email protected] Subject: Re: [LTspice] Model of BF970 ? Hi All, In the

Hi All, In the uploaded file test.asc, I’m having a problem with a simulation getting stuck. Would appreciate a look. Thanks, Chris

I've learned there's two anti-RIAA filters you put at the input of preamp to be simulated: the laplace on and and RC passive one. All my sims with RIAA premps have the passive filter at the input,

Hi, i have been interested in bipolar NDR devices similar to the Lambda-Diode and did some basic simulations which i can share later, if there is interest. I can also recommend the publications by
