Amplifiers: characterization and modeling of nonideal behavior#
Amplifiers: modeling of port isolation errors
At an early stage of the design process, we use relatively two-port models that describe the functional behavior of the amplifier. However, it is important to know the conditions under which electrical networks can be represented by such two-ports. If such conditions are not met, more eleborate description models are required and deviations from the ideal behavior should be well defined.
Presentation
The presentation "Amplifiers: port isolation errors" shows that the set of performance parameters that describes port isolation in practice, is often incomplete.

Noise in electronic circuits
As all real-world systems, amplifiers add noise to the signal.
Presentation
The presentation "Noise in electronic circuits" briefly introduces noise mechanisms in electronic components and presents models and parameters for characterization of the noise behavior as well as noise analysis techniques.
