Amplifiers: types
Electronic amplifiers are often used to interface with sensors and actuators. The nature of the input signal of the sensor or the output signal of an actuator, and the pysical operating mechanism of such transducers, tell us which electrical quantity (short-circuit current or open-circuit voltage) needs to be selected at the input port or at the output port of the amplifier.

Amplifiers: modeling of the ideal behavior
Conceptually, amplifiers are intended to behave as linear, time-invariant systems. Although the supply of power is essential for their operation, the power port can be omitted when considering its functional operation only.
Presentation
In the presentation “Amplifiers: modeling ideal behavior” we will elucidate the use of the transmission-1 two-port representation for modeling of the functional (conceptual, or ideal) behavior of amplifiers. The use of these parameters results in clear design conclusions for making the source-to-load transfer independent of the source impedance and the load impedance. This is of particular interest if the voltage-current relation of the source or the load has a (partly) unpredictable character.

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 preformance measures for port isolation, that are used in practice, are ofen incomplete.

In electronic information processing systems, amplification is one of the most important basic functions. Since the basic amplification mechanism, as it is found in biased ‘active’ devices, suffers from many imperfections, negative feedback is often exploited as powerful error reduction technique.
