Free EDA: Design and simulation with LTspice · One Transistor Before drawing the schematic and designing the PCB we need a circuit idea. Then we will use the free circuit simulation software LTspice to simulate our design. This is what this article is about. LTspice is developed by Linear Technology and it runs native in Windows and Mac OS X. The Windows version runs without issues on Linux using Wine. LTSpice tremolo effect simulation | All About Circuits I am writing because of the issue I have during simulating of Tremolo effect in LTSpice software. My schematic that I use shows picture below: The problem is the fact that LTSpice does not simulate this effect at all. It is so strange, because I have built a physical effect based on this schematic and everything works good. Oscillator simulation in LTspice | All About Circuits Thanks again. Copying how to do it was a little bit tricky as I found that the parameters of the AC analysis must be entered before the transient parameters to get the simulation to work. It looks like the only way that I could determine harmonic distortion would be to simulate band pass and notch filters connected to the output of the oscillator. LM386 LTSpice Simulation | All About Circuits I am using the LTspice model you send me. I attach the picture with the simulation and the circuitry that i'll use after all. Actually, i just added an RC low pass filter to the noisy cricket, with its resistor choosen at 47K to attenuate the input signal a bit. LTspice simulation | All About Circuits Hi.. Thankyou very much for your time..that was really a big help to me..I will check on the LTC4444 driver. But the gate pulses for the higher side GaN G_H is more of spikes, I doubt on the gate drive transformer circuit, which I have edited further but couldn't fix. 4 20mA Current Loop Simulations | All About Circuits I thought I would try and simulate the circuit but am having trouble getting LTSpice to work with my negative voltage references. I've attached a copy of the pertinent portion of the actual circuit, and image of the simulation circuit that won't run and the LTSpice schematic and a snapshot of the transistor base voltage. Thanks is advance. puter Modeling of Electronic Circuits with LTSPICE LTspice IV • A freeware circuit simulator (Windows or *nix Wine) • Netlist syntax is powerful but hard to visualize • LTspice has schematic capture and is much easier to use than traditional text based SPICE.
