mosfet level 1,2,3?
Just wondering what it means when a mosfet is level 1 or 2 or so on. Im designing a comparator using B2 Spice and from what i can gather i can not adjust the W/L ratios of the models supplied with the program. To input the W/L ratios i have to design a mosfet from scratch. ie. need to input all parameters required for a mosfet. I need the right parameters for 0.18um technology. I cant download separate models for this program. Is there a good website where i can just copy paste paramters from like a datasheet or something.
Cheers
