https://hackaday.io/project/16616-your-mosfet-is-not-good-enough-then-modif= y-it A Hackaday post suggests that a MOSFET's gate threshold voltage can be perm= anently shifted by applying a one-time momentary gate overvoltage. "Turn your normal MOSFET into a low-threshold MOSFET in seconds" Sounds like poking holes in a condom to me - not a good idea :) Bob --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
