Please upload your .asc schematic file. The .asc schematic file is needed to troubleshoot your simulation. Howard raymond wrote:

Hai.. Guys. I'm doing on UcD class D amplifier based on Philip UM10155 . I'm having problem in oscillate the UcD amplifier in order to simulate the desire sine wave . My Vin is 5V sine wave , with the

Rob, It will step through all 9 combinations. If you do not want all of the combinations and wish to select the combinations used, see Files>Tut>stepping to the max. It has examples of stepping sets

If I have several parameters which I am stepping in a simulation, does it go through all combinations? For example, if I step a resistor, Rxx, in 3 steps ... and also step a capacitor Cyy, in 3 steps,

I need a modell for LM4041-ADJ (National). Please help me.

Hello, You could use "time" in an equation for the resistance. Instead of the value 10 for example, you write an equation as shown below. R=10*(1-0.9*u(time-2m)) Resistance versus time in this case:

Hi, I am trying to figure out a way to plot gm/Id for a transistor within LTspice. I am using as a starting point the schematic in the example MOSFET parameter sweep, MOS_gm_gmb_gds_ro.asc , within

How can I implement a (time dependent or automate) continuous variable load resistance for simulating various regimes in cc circuit and power dissipation in circuit's components. Thank you!

Hello, You can add comments (e.g. the date) to plots in the waveform viewer. Plot Settings -> Notes and Annotations -> Place Text Now you can use "Tools -> Copy Bitmap to Clipboard" to get the picture

Hello Helmut, "This file contains a PowerPoint file(.ppt) with Mike's presentation. Please open this ppt-file in the presentation mode. Then you can directly open the hyperlinked examples by clciking

Hello Helmut, What are you meaning by " LTspice uses the whole screen. " ? As you can see in my little benchmarks, there a big difference between mini and maxi ? And I deleted some curious results. In

just kidding seriously, I mean it, I would pay someone to generate some transistor models for me. SERIOUSLY. There's no point in me trying to do it myself, it would take a year and I'd never get it

Hi Howard, You're right. The first Models of 555/556 was from the LTspice "Masc." folder. The second attempt was the transistor realization from LTspice's /examples/Educational NE555.asc, following

Hello "????", I made some benchmarks on my PC. I made an excel file. Are you interested ? How send it on the group ? Regards, Philippe

Thank you very much! That was the problem. Runs just fine now. A tip of the hat! Paul
