Solid State Devices Final Review

Transistors are used as small signal amplifiers and electronic switches.

The primary function of an amplifier is provide gain.

The simple formula to calculate gain is Input over Output.

The term doping is the process of removing impurities from pure Silicon to produce semiconductors.

The three parts of a basic transistor are emitter, base, and collector.

When a transistor is used as an electronic switch, we are able to apply a small current to control a much larger current.

The schematic symbol of a PNP transistor shows the emitter lead arrow as "Not Pointing IN".

It is possible to test a transistor using a DMM.

In large power transistors, heat sinks are attached to the transistor housing to help dissipate voltage.

The typical bias voltage of a PN junction is around 0.6V.
