vedhaanth648, I uploaded your file for you.? It is in the Temp folder. BSS138.zip ( /g/LTspice/files/Temp/BSS138.zip ). To answer your question "i dont know which one to use", use

Please do not point us to some random website that has your files, even if it is your own. *UPLOAD* your files to our group's Files section, into the "Temp" folder:

Please DO NOT send us to third-party sites for data. Upload your .ZIP to Files => Temp, and then tell us you did that. Meanwhile, you mean BSS138, not BS138.? The way to add third-party models is

i have the following 3 files related to it. BSS138.zip ( https://tinyurl.com/bdb9bb2d ) i dont know which one to use and which standard component to use in place of this component

Re: can the Sam Ben-Yaakov self-adjusting switched-capacitors 4 cells balancer, economically manage 104 cells wired in series?
I got the impression that the switching mechanism is essentially the same as he describes in a 2008 lecture on SCC, at https://www.youtube.com/watch?v=2HlF5ZhCWXQ, where at about 55 minutes into the

Re: Plotting expressions in LTSPICE
Thanks for the quick reply. Pls find below the answers to your queries: Pls read the value of Cox as 8.5fF/um^2. It is the oxide capacitance per unit area. While implementing the formula fT =

Re: Plotting expressions in LTSPICE
What you want to do can be done. Note the following: 1. In the Cox formula, LTspice stops parsing after the 'f'. What is 'u' anyway? Is it a fixed voltage? 2. You say that the y-axis unit isn't

Re: can the Sam Ben-Yaakov self-adjusting switched-capacitors 4 cells balancer, economically manage 104 cells wired in series?
Surely this is not Sam Ben-Yaakov's intention, as he readily describes a natural self-balancing behaviour (propagation indeed) permitting the use of 2 switches per cell in case it is acceptable that

Re: ISL70444SEH declaration issue?
It helps if you upload a schematic that actually runs. You have a ".lib ISL70444SEH.lib" directive in the schematic, but the model file you uploaded is "ISL70444SEH.cir" and there are no analysis

Re: ISL70444SEH declaration issue?
This happens sometimes where there are signals with fast edges (aka zero rise or fall times), discontinuities or indeterminate derivatives. An indeterminate derivative happens at a corner. See if you
