I'm building a full-custom CMOS circuit for a client, and need a power on
reset cell.  You know, logic 0 out until the supply exceeds the trip level,
then logic 1 until the supply goes delta below the trip level.

I've come up with one, but I know I could do much better with more time.
Rather than spend more time (pretty expensive right now) I thought I'd find
out if anyone knows of any papers or other descriptions of such beasts.  I
don't want to futz with bandgaps and resistive dividers.  Just something
simple, well controlled, low power at full supply, using P and N fets only,
and already demonstrated.

Thanks;
