Flicker Noise Current: I_FLICK



I_FLICK models flicker noise current. This is a nonwhite noise source.


Name Description Unit Type Default
ID Element ID   NS1
KF Flicker noise coefficient   1e-14
AF Flicker noise exponent   1.0
FFE Flicker noise freq. exponent   1.0
COMPAT Model compatibility selector   AWR (bias current)

Parameter Details

COMPAT. Allows toggling between different behaviors: the behavior corresponding to the Cadence® AWR® implementation of the model, COMPAT=AWR (bias current); the ADS compatibility mode of operation, COMPAT=ADS (noise amplitude modulation disabled); and COMPAT=Conversion matrix approach noise modulation.

Implementation Details

The flicker noise current flows through the N(I) branch and is dependent on the current in the I branch. The spectral density of the noise current, S(f), is


where Idc represents the DC component of the current in the I branch.
