Appendix 3

Specific Topologies with Transistors

A3.1. Common-grid and common-drain topologies

A3.1.1. Common-source topology

Hence:

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

as well as the correlation matrix:

A3.1.2. Common-grid topology

So we can write:

That is:

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 ...
