Here is the way these three parameters are most commonly used in these (and similar) models: * Speed allows you to choose a relative speed variation.  Speed=1 is for a nominal (typical) part.  It

Oops, I meant to say " *74LVC1G74*. Jim

I need help setting up the 74LVC1g74 Flipflop parameters for 5V operation. From the 74LVC1G.lib file I get the following

In order to tune crossover distortion, the best is visualizing linearity. Distortion percentage doesn't indicate what to adjust.

It's in here: Files > Temp https://groups.io/g/LTspice/files/Temp which is where all newly uploaded files are. Andy

Mike, Thanks a lot, kindly share the uploaded link here.

Yes, I know. I have already uploaded such a schematic example <https://groups.io/g/LTspice/files/z_groups.io/Examples/Apps/THD%20Notch%20Filter/THD_Notch_Test.zip> using one a few years go. It doesn't

To evaluate and quantize crossover distortion you can use a notch filter (RC bridge) to eliminate the fundamental frequency out of the output voltage. ritecom.com@groups.io> wrote:

The best way to handle different simulations, is to name the schematics differently.  Say, MySim_Tran.asc and MySim_AC.asc, which might be identical except for their simulation commands.  Then each

As you know, this group is not the place to officially make suggestions to the LTspice developers about recommendations or improvements.  This group is people like you who *use* LTspice; we are not

Hello, Some additionals features : Some options for future releases. Christmas is over, but it will be for next year:) - MultiTabs per plot setting could be very nice, especially when we changed

If your amp is in a high gain negative feedback loop, it can be harder to see the crossover distortion because the feedback look "eliminates" most of it.  Getting rid of that feedback would make it

Yes. To "see" it, as a distorted- looking sinewave, you need to make the distortion bad enough so that it stands out.  Visually looking at sinewaves, they generally need to be pretty bad for humans

You can also do this with a .DC analysis. With this it's also very easy to do a "wingspread" plot, which plots the incremental gain, which is very revealing. -- Regards, Tony

...and apply a very low input signal when running the transient test.

1.Use.TRAN analysis, not .AC, because that doesn't show non-linearity. 2. Check that the current through the output devices is very small with no input signal. -- This email has been checked for

If I build a Class B amplifier (all have cross over distortion) What do I have to do, to see cross over in a trace... All I get is a perfect looking sign wave... What would be the analysis and steps

Dave, I just uploaded the file "MF_VCpot.zip". I got tired of trying to allocate floating net names to different pots. I chose the pin name as "PC", because it is the Pot Control pin. Feel free to
