Hi Andy, right now I found the CD4060 model in ToC, thanks.

Hello, Even log(0) is a big problem. The result be -infinity which is useless in a real circuit. That's why my suggested IF() has used a limit of 1e-6. Best regards, Helmut

Hi, Helmut: Thank you for the suggestions, but if I use the IF() as you mentioned, x couldn't be recovered as it was before compression. But your answer seems LTspice couldn't treat the negative value

4063 is a 4-bit magnitude comparator (for comparing the dimensions of 1 dollar bills?), so is a purely digital device and not very suitable for Spice simulation at all. Best wishes John Woodgate

Hello, ES. It's not easy to interpret your musings on space-time, but in your first paragraph you actually ask for two different, but related, things. There are many textbooks on semiconductor theory

Hello, You have used log() from negative numbers. Normal calculators will fail in this case. I recommend to use an IF() to workaround. V=IF(V(x)<1e-6,0,log(V(x)) Be aware that log() is the same as

You know, if my window could tolerate a swing of 100, this method will help avoiding ruin my window. Since the swing could minimize from 1Mega to thirteen degree. Wouldn't you like to know the answer,

Hi, : Please help, do you know how much powerful this will help, it could minimize the numerical value from 120dB to number '13.8155'. Which help to plot/sketch them in a single graph. Where stores

Hi, : While I am thinking using a mathematical compression (limit the numerical values to a scaled range, then revert them) algorithm, I found that in the BV device, the exp(), log() (natural

Hi Juan, The CD4060 is there in the files. There are several locations. You need to *unzip* the file. In one of them you will see the symbol and the subckt with a test schematic. But the subckt is a

Hi Bordodynov, Thank you for your model of MC34074P. We have been using thousands of the MC33074 and MC33072 in our boards. I designed the old school way of actual breadboarding and pcb proto before

Hi Andy, I like your suggestion. So now my backgound is dark gray! I'm ok with seeing the icons. So no problem whatever my default settings are. Hi Bordodynov, I have used another of your models. I

Also, sometimes when I came cross the streets, I saw some ignorant little boys playing and sitting fat men aside , I always hope/remind myself, I should fulfill my mind soul, brain more, such that I

Hi everyone I need CD4060 and CD4063 LTSpice models, .subckt and .asy files. Thanks in advance.

Hello, John: Thank you for the replies. Though several days ago, I would like someone could suggest some materials (textbook) about the semiconductors, electron-hole pairs, carriers, etc. Everything

Hi analogspiceman A comparison is good idea - here it is. https://groups.yahoo.com/neo/groups/LTspice/photos/albums/66673444/lightbox/23103296?orderBy=ordinal&sortOrder=asc&photoFilter=ALL As

I have read the paper, and I recommend reading it, as it is very well written and fairly easy to understand. I agree with Andy that the voltage source should be applied at the left end of the line,

Hello Andy. I occasionally have this situation (an additional extension txt is added). It annoys me. I do rename (delete txt). But since I rarely download models (I already have a lot of them), I put
