Hello Alan, I have connected the loopgain-probe directly at the output. Now it looks better. See my uploaded example. Best regards, Helmut

But you can see the opamp local loop is closed.

The op-amp gain from -In input to output is about 96dB. Andy

Hi I am encountering another problem of simulation. I just up loaded the .asc and the model files. This is a simplified version of a hybrid amplifier that has opamp as first stage and followed by two

Thanks Andy.

Thanks Helmut.

Dan, the feature ("Place .OP Data Label") was in LTspice IV too, but it doesn't go back to LTspice's beginning, so very early versions (MANY years old) did not have it. The Changelog shows that it

O.K, thanks for your answer. I am going put it in practise.

Hello Alan, LTspiceIV Run the simulation. Right mouse-click into an empty area. Choose View -> Place .op Data Label LTspiceXVII Right mouse-click into an empty area. Choose Draft -> Place .op Data

Hello PhB, that's exactly what I was looking for! Thank you very much! Best regards, Markus

I'll reload the VXII again soon, right now, I am just using IV to get things done first. I have a simple question, how do you display the DC voltage on a net. I just forgot, right now, I just use F6

Hello John Woodgate. I do not mind creating with you the scheme you need. This topic is in my interest. It is bad to have unspent potential. I have already helped other people create amps. Therefore,

Alan, Is it possible that the .raw files from the two runs are colliding with one another. I don't think its a good idea to run both programs at the same time on the exact same .asc file. I think this

Hello, I just got feedback from Mike. Unfortunately Mike will be out of office for a couple of weeks. Thus it will take some time until he can fix this bug. Best regards, Helmut

Hello Vlad, I do not have the best relationship with Mike because he is still angry that I used to write about some of the inner working of LTspice (even though I did it out of admiration and not

Hello all, I have previously used this when at Uni but really need to get more involved - is there some gentle guide on how to get different models going for LTSPICE? My understanding is that there

I just ran it on both LTspice IV and LTspice XVII. The two are the same as one other at every point, within about 10 digits (<0.0000000001dB, <0.000000001°). Windows 7. Andy

Is anyone willing to help me by private email with the design of an amplifier (not Class D) to drive a 300 mA sine wave into a 170 H load (5 ohms resistance) from 40 Hz up to 150 kHz? It needs to be a

Hello, I forgot to mention that I have uploaded a modified version of your circuit with this modification of the SR-flipflop. SpiceLine: td=10n Simulacion_Fuente_COG
