Hey all
I have recently become quite intrigued with negative voltages and have been playing around with different ways of creating them
One way I have been doing this is with a charge pump. The issue with this route is that they don’t produce much current.
I am wondering, is it possible to somehow increase the current with an higher current positive input?
I am probably doing a terrible job of explaining this in words so please see the diagram below
The exact numbers are arbitrary and am more just wondering does the “Current amplifier thingy” exist?
If feel like the answer is going to be really obvious and either going to be “of course you can you idiot, just use an op amp / whatever” or “No you dingus! That would go against the laws of physics because X” but I can’t work out which one it is
Sorry, this is probably a really dumb question! Negative DC voltages are really quite new to me so I am probably missing the basics (even with stuff like when to use negative numbers into the data sheet formulas is tripping me up at this point
)
Thanks in advance
