Canali Velocity Saturation

Model

Below example would be used for velocity saturation along the channel of a MOSFET where "y" is the channel direction.

proc mobility.canali { $Emob_low $Hmob_low } {
set vsatn 1.07e7
set vsatp 8.37e6
set Emob_Canali "$Emob_low / (sqrt(1 + ($Emob_low*dot(DevPsi,y*1.0e-4) / $vsatn)^2))"
set Hmob_Canali "$Hmob_low / (sqrt(1 + ($Hmob_low*dot(DevPsi,y*1.0e-4) / $vsatp)^2))"
}
