FYI - Op-amp GBP or bandwidth is only one consideration. Also there are the effects of the external components, such as the feedback capacitor, the output load, gain-peaking, etc.. Also slew rate.?

Thanks Tony et al. I did totally flub the initial file upload. I've moved on to using this opamp for my intended purpose, as a TIA that can pass pulses from a photodetector. I'm not getting what I

I just went to diodes.com and found the newest spice model for the BSS138. ( https://www.diodes.com/spice/download/1838/BSS138.spice.txt )

Then start with the simplest circuit of a single stage, then add stages until it disproves the conjecture. Tim

IMO, you are wrong, Tim. The video is about a quasi-continuously varable step-down DC/DC converter. Concerning his self-adjusting autonomous 4s battery equalizer, Sam Ben-Yaakov described a natural

The files are dated, use the most recent one.

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

OTOH, we don't even need a calculator to compute the MTTF of such a circuit. -marcel

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

Funny thing is, that I filed a patent, way back in about 2007 on balancing ‘energy storage devices’ using a switched-capacitor mechanism… US 7,994,756 B2 have a fine day, all… Barry Rowland
