I have repeatedly shown how it is quite simple to model transformers with cores with hysteresis loops. I posted the models on LTwiki. I have many examples of circuit calculation. It surprises me that

I think my example with diodes will be useful to you and only you. The effect of spice parameters on the reverse current of the diode. See file ExampleDiode.zip in TEMP folder. Bordodynov.

There are different ways to determine the stability of an amplifier. And there is a simple way, more understandable, derived from the theory, which is discussed in textbooks. I used the possibility of

I put a small transistor in my version, and not as in the original electronic circuit. Capacitors of the order of 1 picofarad are placed in filters on switchable capacitors. Dynamic memory chips use o

Hi. Yes, as mentioned here, I have an error in the last output. Since the original circuit did not work with 8 V power, I corrected the numbers to 7.9 V.

An alternative was proposed - adding your own files with models, with file names other than the standard ones. And then when you select, you select from the summary file. There were messages and I ask

Hi. I downloaded models the RF N-CHANNEL VERTICAL DMOS MOSFET. It's better than nothing. See the polyfet.zip file in the TEMP folder.

Hi. I had to model an old circuit in LTspice24 (needed to recalculate some things) and it didn't work. I had to force TRTOL=1 to make it work. I came to the conclusion that the previous value of TRTOL

Hi. Generally speaking I don't think floating land is necessary. It is possible to calculate circuits without it. But especially for stubborn people I have created a model of floating ground and a sym

I decided to calculate the old circuit and found a very unpleasant fact. I could not calculate the transistor power. I could only see the collector current. The emitter and base currents are not shown

I solved the problem by reinstalling the program.

Hello everyone. LTspice 24 does not see my user.* files. Please help me. bordodynov.

I have uploaded your schematic calculated my way. I have two kinds of windings in my library. One without leakage and one with leakage. The second option increases the calculation time a bit.
