I found out what's wrong with my model definition. It appears that the ETA parameter of the level 3 spice model can not be less than 1, even though the default is 0. I'm wondering what this parameter

Hi all, I'm trying to simulate a very simple 3 stage differential amplifier in LTSpice. The design works well in Hspice. However, when I try to run it under LTSpice, I got the following output in the

Hello all, Let me first thank Linear for such a nice spice simulator that too free! I am relatively new to this field and have a requirement to simulate a circuit based on INA 103 IN AMP from TI. I

Mike, could you add the ability to print the DC Operating Point information from a .op run? I know that I can cut and paste to a text editor, but a print command would be easier.

Thanks for the example. It looks like the problem only happens when ploting expressions of stepped data of complex data. I'll publish the fix in a few days. Thanks again for the report. --Mike ---

Brad, Could you send me the file(s) I need to duplicate this. I'd appreciate it. --Mike __________________________________ Do you Yahoo!? Yahoo! Calendar - Free online calendar with sync to

While using the .step command to sweep parameters, I am getting extraneous lines in the waveform viewer that go from the end of one trace to the beginning of another trace. This only happens when

Thanks Mike, The problem is probably related to the fact that the input reference is also the output reference. I have solved the problem by using a voltage-to-voltage converter with unity gain. The

Steve,

Gentlemen - The modulator block is a special function that is relatively undocumented. I find it quite useful as it would take many primitive functions to perform the same function. I have been using

Hello Helmut, thank's a lot for the quick help. Thank you also for forwarding the thread with the detailed information about FFT and simulation points vs. FFT points. This will definitely help to

Mike, Thanks for spending time on this. All appears good now. (I don't know what I was doing wrong on #1, but it works fine now.) For #3, that is a good way of handling it so we can get reasonable

Brad, Thank you very much for sending me the schematic to my other account. This looks like a pilot error. In the appended .asc file, node X and node Y are two different ways of recombining the

I found the following issues while working on the attached circuit. There are easy work arounds for all of these, but they are something to be aware of. (Some may be caused by operator error.) Brad

Hello * I want to do distortion analysis in the audio frequency range. This means I would like to simulate down to 0.00x percent distortion products. Frequently I end up with ca. 1% distortion just

Mike, Thanks for the quick response! LTspice is a fantastic program, and you provide best support of any software! You are providing a tremendous service. Brad polarity. ---

Brad, My high speed connection just came back up so I was able to update the web leaving for the weekend. Just do Tools=>Sync Release to get version 2.03f which has the behavioral current source
