Channel Thermal Noise

Two models exist for channel thermal noise. Each of these can be toggled by the noimod flag.

For noimod=1 and 3,

(-212)

where gamma is a new model parameter introduced to model short channel device thermal noise. The default value for gamma is 2/3.

The standard Berkeley BSIM3v3 equation is

(-213)

For noimod=2 and 4,

(-214)

where Qinv is the channel inversion charge, and is calculated as follows:

• For version 3.1:

(-215)

• For version 3.2, the Qinv equations are described in Intrinsic Charges.
