Shot Noise Current: I_SHOT

Symbol

Summary

I_SHOT models shot noise current.

Parameters

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.
