Can anyone tell me what are the units of area parameter used in ngspice?

The units of "area" can depend upon the device. For diodes it is the physical area, for MOSFets it can also be M or the scaling factor. This is because in MOSfets the L and W can be used to calculate the drain and source areas (or you can give AS and AD in square meters directly - Si units), so M is used to scale for # of parallel devices when areas are not given directly.

  • \$\begingroup\$ I am asking in what units do we actually specify the area i.e. whether in meter-square or centimeter-square \$\endgroup\$ – Madhusudana Nov 27 '14 at 5:46
