Thank you very much for your help. Chances are good that the photodiode part is smaller, so it might be easier to single it out. It might be as simple as one line in the model file, or it could be doz

Thank you very much for your advice. Because of NDA with the company I got the file, it is difficult for me to upload the file. Can I find any example where the lib file is separated according to the

Thank you very much for your comments. Actually because of NDA with the company I received the file, I can not upload the lib file. Can I find any example where the lib file is separated according to

Hi I got a .CKT file and .lib file of photodiode and transimpedance amplifier. I know how to make spice model from these files. However, I want to separate transimpedance amplifier part from the .CKT

Thank you very much for your help. According to your comments, "When you ran the S-parameter-to-SPICE conversion program, what you got was the SPICE model.", Yes, when I run the S-parameter-to-SPICE c

Actually I got s parameter files for a transimpedance amplifier. What I did so far is, I converted this s parameter file to .lib file by running that exe converter in command prompt. Later I generated

I have a question regarding this. If we have s parameter of a component (op amp as example), if we can convert it to spice model , can it work as am op amp in spice simulation? In that case, can we ad

Yeah I know that LTspice has several op amps. Probably all are from Analog Devices, right? I contacted some manufacturers and they replied that they do not have SPICE models. Thank you very much.

I want to build spice models of high speed transimpedance amplifier. There are many op amps in LTspice simulation. However, I am looking for very high speed TIAs from other manufacturers. They have ma

Thank you very much for nice explanation.

Thank you very much for the nice explanation. So I came to know that the LTspcie results do not show phase margin. It is phase response and I need to add 180 degree with this to get phase margin. For

Thank you so much for your nice explanation. Thus less than 0 degree phase margin represents oscillating (instability)? i need to consider 180 degree (plus or minus? ) with that phase appear in LTspci

Hi, I would like to know how to know how to determine circuit stability in LTspice. I found some docs said that one of the simplest ways way to determine the circuit stability is that by applying an a

Highly appreciated. Thank you so much for the valuable advice.

Thank you so much for the nice explanation. It is really helpful I have learned a lot.

Hi Is there built in band pass , low pass, high pass filters in LTspcie like in Pspice? I am looking for built in filters (not making RC based filters). Thanks in advance.
