Flicker Noise

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

For noimod = 1 and 4

If wnoi is given

(-202)

otherwise

(-203)

For noimod = 2 and 3

V_gs > V_th + 0.1:

where V_tm is the thermal voltage, μ_eff is the effective mobility at the given bias condition, L_eff and W_eff are the effective channel length and width, respectively. The parameter N₀ is the charge density at the source given by

(-204)

(-205)

The parameter N_l is the charge density at the drain given by

(-206)

(-207)

ΔL_CLM refers to channel length reduction due to CLM and is given by

(-208)

(-209)

Otherwise,

(-210)

where S_limit is the flicker noise calculated at V_gs = V_th + 0.1 and S_wi is given by

(-211)
