Amplifiers are circuits that are used to increase an input signal, thus you can obtain an output signal with much greater amplitude than the original one. Amplification is the process to increase the magnitude of a signal, generally using an amplifier.

The bipolar transistor is an electronic device that originates a big evolution in the electronics field. The basic features of the bipolar transistor are introduced on this topic. We'll study the basic model (Ebers Moll Model) of these devices and their use in the analysis of circuits biasing.

MOSFET Transistors or Metal Oxide-Semiconductor (MOS) are field effect devices that use the electric field to create a conduction channel. MOSFET transistors are more important than JFETs because almost all Integrated Circuits are built with the MOS technology.

It is known as Joule effect to the phenomenon by which if in a wire circulates an electrical current, part of the energy is transformed into heat. This law (Joule's Law) is named after the British physicist James Prescott Joule.

Relay was invented in 1835 by the US scientist Joseph Henry (1797–1878). Relay or elecromagnetic relay is a magnetically operated switch that is activated or deactivated when the electromagnet is energized.

At the present time the radio frequency spectrum is becoming small for the growing demand for telecommunications. The incursion into the field of microwaves is natural and we must also take into account that there are some applications that are unique to the microwave frequencies.
