Hello!
I've got a bit of a dumb question. I'm using LTSpice for simulation of simple shifter which takes 0V or 3.3V as input and gives 0V or 5V as output. Here's my scehmatic (the image is way too large): http://i62.tinypic.com/16jrjmw.jpg .
When doing simulation I view the voltage on R2 and it's -4.7V instead of +4.7V or +5V.
What am I doing wrong? What must be changed to get positive voltage on R2?
Thanks.
