LTspice is a SPICE-based analog electronic circuit simulator computer software, produced by semiconductor manufacturer Analog Devices (originally by Linear Technology). It is the most widely distributed and used SPICE software in the industry. Though it is freeware, LTspice is not artificially restricted to limit its capabilities (no feature limits, no node limits, no component limits, no subcircuit limits).
Hello!
I'm trying to model common mode current with LTSpice, but there is a problem with my simulation. Someone else tried on an other software and got the expected result, but I can't explain why. When going through the capacitor, square signals should become pulses, but that's not the case...
Summary:: I'm trying to analyze a frequency-mixer circuit using LTSpice but i keep bumping into problems. Am I understanding something wrong?
so I'm trying to design a frequency-mixer circuit. (the images are all shown below) in LTSpice, and there's a task asking me to perform a transient...
I use this netlist and simulation result came out as shown. I need to find the dc gain here and circuit diagram, but I'm not sure how. I would be very grateful if you could give me the answer.
The time domain analysis is easier to plot compared to analyzing the frequency with respect to the phase. But, LTSpice makes it look really easy. So, for a small signal AC analysis, LTSpice does use a AC voltage source for its frequency domain analysis function. This must be a really convenient...
Can secondary cell can be described in circuit simulator?? With other symbols like capacitor. Also I wonder if there's a program that provide secondary cell(like Li-ion battery). Please help me
Dear forumers,
I have two high performance AC feedthrough capacitors (47nF, 100A, class Y2, DC-60Hz) which I want to either combine with a general purpose EMC line filter, or build a custom one to filter the mains from of about 100khz to as high as possible (for shielding purposes).
I can see...

Hello,
We just finished up midterms and I actually did well--got an A. However, somehow between the midterm (class before last) and last class we jumped to creating a circuit with a diode. I am pretty lost.

I am simply attempting to design a circuit in LTSpice. We just started on dependent sources.
I am having trouble designing this guy here:
Here's what I've got:
What does this error mean?
What do I need to change to make this circuit work?

Hi. I have a simple circuit with a third-part model. As far as I can tell using info from the internet I have everything correct, but I still get this problem. Please help me clear this log-jam, thanks!
