<Snip> </snip> Hello Micheline, All of the parameters of the diode model are explained in the LTspice>Circuit Elements>Diode section of the Help. Regards, Tony

Where did you last leave it? :-)

Ian, With respect, we don't know for sure where the circuit should be grounded, as we don't know what the application is. Perhaps the rectified bit should be floating? Regards, Tony

Hi, I had tried the "Diff-amp-based delay element" simulation on ltspice but i couldn't get the results.Can anyone guide me what I did wrong while circuit design. Please find the files - I have

Hi dinesh. May help link: http://www.mosis.com/test/ There is this: IBM 0.50 micron (5HP, 5AM, 5DM, 5PA) IBM 0.35 micron (5HPE, 5PAe) IBM 0.25 micron (6HP, 6DM, 6RF) IBM 0.18 micron (7RF, 7RFSOI, 7WL,

Hello Micheline, The result of both solutions is the same. Please take a look to the enhanced version. Files > Temp > Pefficiency_analysis-1_abc.asc You have to plot the voltage difference V(a,b) at

Can anyone tell me where can I find the file "tsmc90.lib" Thank you.

Hello AG, You could make an FFT of the signal or you use .MEASURE commands. Please take a look to the examples. Files > Tut > MEASURE > TRAN Best regards, Helmut

Hello Desmond, This SINE-symbol is available in the LTspice component's selection. F2 [Misc] signal Best regards, Helmut

The symbol is just a symbol ... an icon. You can draw it any way you want. It makes no difference whatsoever to the simulation. You could go into the symbol editor and change it to anything you like.

It looks like some body modified the symbol for a voltage source. If you control + right click on the voltage symbol you get the "Component Attribute Editor" dialog. In the upper left corner Click on

Thanks Tony. I learned a lot. Landrum

Hi all, Just joined this group a few days ago and I'm quite surprised at the level of traffic on this list. I've been a VLSI design engineer for 21 years and am currently using Cadence tools

Nope im referring to the "symbol" of the voltage source located in the left diagram not the results... *note that there is a sine wave in the symbol itself.. I found the left side diagram somewhere,

It works for me! What do you get? We can't fix something if you don't tell us what seems to be wrong. I get a nice sine wave with +/-230V amplitude and 20ms period. You can improve the accuracy of the

How do you measure frequency of an oscillator accurately in LTspice..( I probably need this for .disto to work well) cheers AG

Hiya Heinz I am sorry but I have to disagree. My approach is to have the databases loaded with all the possible parts that I may use. The only time that I hand draw a circuit diagrams now, is on a
