Bias-dependent Noise Current: I_GEN



I_GEN models a general bias-dependent noise current. With a proper choice of parameters, it can represent thermal, shot, flicker, or burst noise.


Name Description Unit Type Default
ID Element ID Text NS1
P1 P1 parameter   0
P2 P2 parameter   0
P3 P3 parameter   1.0
P4 P4 parameter   0
P5 P5 parameter   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 spectral density of noise current through the N(I) branch, S(f), is


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