Is it ok if I can use 0.18u length for my transistors? Im trying to reach 10Ghz but its too difficult. --andrew

Click to expand... of course contact is large than lmin but you never place contact over gate you extend gate beyond active and add m1poly contact

I believe lenght has nothing to do wiht contact size as far as layout to be considered...
