Wow!!! That was a really quick reply. I am alwayz amazed by how quicky I get answers here
. So thanks again and yes I did try disovercircuits.com. Actually I need a mos transistor level implementation circuit. That is why I started with my books but unfortunately they don't have a lot of information either. I use books like Holberg, Razavi, Baker Li Boyce, John Martin etc for analog CMOS and these like I said dont have much info on window comparator. But I will look in this forum to see what I can find.
Thank you.
