Fingers and multiplier of MOSFET

jun1119

Hi 

What is the meaning of finger and multiplier in a MOSFET as we can see in the properties of a MOSFET?

I would highly appreciated if there are some diagrams and layout to be shown.

Thank  you

  • Hello, I generate a schematic with a single MOSFET and set the multiplier (m) to 8. However, when I generate the layout from the source, Layout GXL brings me a single device, not 8 devices with the same size. When I run LVS it fails and tells me that the properties of the devices do not match (the device in the schematic view has 8 times larger width than the device in the layout). What can be the problem with this m factor and generating the layout from the schematic source? Thank you very much in advance for your answer.
