As asked in the header, does anybody have an idea for simply generating
a low negative voltage for indicator leds on low output voltages e.g.
0.9V on FPGA core supplies ?
Non-red leds (green, yellow, white) need at least 2V or more so a direct
connection to low voltage regulators for indicating presence doesn\'t
make sense.
Of course a driving NPN could be used however on many voltage outputs a
negative supply would be an alternative.
Using some kind of phase output of buck regulators is one of the
possibilities, is there any other simpler idea ?
Thanks for all suggestions,
Mike
