## Amplifiers: characterization of port isolation errors#

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.

## Amplifiers: modeling of the drive capability and power efficiency#

Amplifiers: modeling of power losses and energy storage

As all physical systems, amplifiers suffer from power losses and energy storage.

**Presentation**

The presentation "Amplifiers: power losses and energy storage" introduces high-level modeling techniques for such effects. It also briefly introduces a classification of amplifiers, based on the operation of the stage that drives the load.

Amplifiers: modeling of small-signal dynamic behavior

As all physical systems, amplifiers impose limits to the rate of change of a physical signal. For small signals with a small rate of change, the amplifier can be considered as a linear time-invariant dynamic system and modeled accordingly.

This presentation "Amplifiers: modeling of small-signal dynamic behavior" briefly summarizes analysis and characterization methods for such systems.
