Base Bias   The simplest form of biasing is to use a single resistor.  A single source provides the biasing requirements of both PN junction...

The photodiode is another light-sensitive device which utilises a PN junction.  It is constructed in a manner similar to the photovoltaic ce...

A further development of the standard LED package is the seven segment numerical indicator and the sixteen segment alpha-numeric indicator...

Light emitting diodes are available in a wide variety of shapes and sizes, and they can be manufactured to fulfil a specific purpose or for ...

The hot carrier diode (HCD) is formed by placing an N-type semiconductor material (usually silicon) in contact with a metal such as gold, si...

When any PN junction diode is reverse-biased, majority carriers are swept away from the diode’s junction...

The forward characteristics for silicon and germanium diodes are shown below. For forward voltages below about 0.6 v for silicon and 0.2 v f...
