Hence:

From this, the admittance matrix and the noise current vector can be deduced:

as well as the correlation matrix:

So we can write:

That is:

images

Similarly:

That is:

From this, the admittance matrix and the noise current vector can be deduced:

A3.1.3. Common-drain topology

A3.2. Cascade association of 2 two-port networks

Consider 2 two-port ...
