Thank you for your response. I have uploaded the pictures of the figures and equation. /g/LTspice/album?id=295221 Please let me know if you can't access the photos. I will really

Unfortunately, many of us don't have access to ieeexplore without paying $$, so we can't see the figure 2 you are referring to. If you are able to, it would help if you could transcribe it into an

Could someone tell me how can I model a SRD in LTspice and use that as a component in other circuits? I am new in LTspice and don't have much idea. I am attaching a link to a paper.

Thanks everyone, OK, Andy I'll look into it now. thanks.

john23 asked, " But its for PSPICE.What could be done to convert it properly into LTSPICE? " Probably nothing. I might be remembering incorrectly, but I think you were already using that UCC21220

Hello, I want to test also the suggested UCC21220A. But its for PSPICE.What could be done to convert it properly into LTSPICE? Or i just need to treat it like LTSPICE and use the create symbol in the

Yes. you can't use ^ fro exponentiation in LTspice,, except in Laplace expressions. Use **. -- This email has been checked for viruses by AVG antivirus software. www.avg.com

The other problem is that you used the wrong formula for a varying frequency. Yes it seems to be that " sin(pi*20e3*time*time) " would result in a frequency equal to "time".? But that is incorrect,

I guess you forgot that "^" means exclusive-OR, not? exponent (except in Laplace). -- Regards, Tony

I believe I solved it by using V=sin(pi*20e3*time*time) instead.

Hello, I am trying to sweep frequencies to 20K with the behavioral voltage source using V=sin(pi*20e3*time^2). I get no error, yet I don't get the same results as I do using a wav file.

For Spice it did not applied for FET but for BJT.?Can be used for oscillator and filter built using op-amp?

Yeah I want an actual purpose-built transimpedance amplifier like OPA855 from Texas Instruments, LTC6268-10 from Analog Devices. However, these can not meet my bandwidth requirements for gate mode

Hello All, Tony, thank you. Mine was the latter. I simply need to disable the four pacing current sources, and maybe enable others, before running the sim. I tried doing IF() inside the PWL statement

Leon, I did as you did in your photo (螢幕擷取畫面 2024-05-21 174809.png), and it worked for me. Of course since it is a Schmitt device, it has hysteresis so it has different actual thresholds
