Add two more series strings of NMOS devices from the OUT line to ground and shift their gate connections around (I'm not gonna draw it). -- Paul Hovnanian paul(a)hovnanian.com ---------------------------------------------------------------------- Have gnu, will travel.

Everybody stands on the shoulders of giants. Blumlein covered a lot of ground in his relatively short life - he's like Einstein in physics, in that when you are digging into something new stuff you run a fairly high risk of running into the name. You do wonder whether it was a relative, but with those two it never is. -- Bill Sloman, Nijmegen
