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

Oddly, some of (what are now) Analog Device's TIAs do not seem to show up within their TIA section of the product selection pages, making their product selections incomplete. I might be wrong, but it

I-sources cannot be behavioural, thus cannot be changed while the analysis is running. Do you need to do that, or can your analysis be .stepped with different conditions applied to each step? If the

All, The VISHAY VOMDA1271 device simulates correctly. The VISHAY LH1262 device fails due to a defective spice model. The VISHAY VO1263 device fails due to a defective spice model. I have submitted all

sorry, i think i find the solution? just setting the vt and vh on the spice line,right?

Hello All, I have four PWL current sources that drive a half-dozen switches to simulate the outside world. The PWL current sources and switches push my simulation through its paces. I would like to

Hello, everyone i want to invert a high level voltage through schmitt inverter , but the data spec show the high level threshold is not as ltspice original setting 50%, so can anyone teach me how to

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.

If I search the group's Files for "TIA", several things come up, not all of which are for TIAs.? And that doesn't include transimpedance amps that don't use the "TIA" abbreviation. If you have a

You asked about making a TIA model from scratch - but did you know that LTspice has some TIAs already? Also, are you certain that the other manufacturers do not have SPICE models?? Some manufacturers

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

I found references for the VOM1271, the other two I didn't find anything for now. From what I could see, VOM1271 is very similar to FDA217, but better documented. -- Carlos Delfino Quem sou:
