Hello,

What is the difference between connecting n number of mosfets in parallel and multiplying the gate width of a single mosfet by n?

When parallelizing a mosfet, with the exception of ohmic resistances, it appears that all current generators and capacitances of the intrinsic model get parallelized too. Since these elements are linear functions of width, it eludes me why the end simulation result is not that same when scaling the width.

Thanks,

Max
