Shot Noise Current: I_SHOT



I_SHOT models shot noise current.


Name Description Unit Type Default
ID Element ID Text NS1
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 shot noise current flows through the N(I) branch and is dependent on the current in the I branch. The spectral density of shot noise current, S(f), is

where Idc represents the DC component of the current in the I branch and q is the charge of an electron.
