Introduction to Transistors

The transistor was initially developed at Bell Laboratories in the year 1948. Transistors are a kind of switch and can be applied to as many electronic equipments. Transistors are...

Diode Clamping Circuit

A clamping circuit is used to place either the positive or negative peak of a signal at a desired level. The dc component is simply added or subtracted to/from...

The Voltage Doubler Circuit

As its name suggests, a Voltage Doubler is a voltage multiplier circuit which has a voltage multiplication factor of two. The circuit consists of only two diodes, two capacitors...

Bridge Rectifier Circuit

The bridge rectifier is one of the most widely used rectifier circuits. It offers a high level of performance when compared to other rectifier circuits. In view of the...

Two Diode Full Wave Rectifier Circuit

The two diode format for a full wave rectifier circuit is one of the simplest forms of full wave rectifier circuit in terms of the actual component count. The...

Full Wave Rectifier Circuit

The full wave rectifier circuit is one that is widely used for power supplies and many other areas where a full wave rectification is required. The full wave rectifier...

Half Wave Rectifier Circuit

Basic half wave rectifier circuit The half wave rectifier circuit can be used in a number of different applications. The half wave rectifier circuit normally utilises a single diode....

Diode rectifier circuit

Diode rectifier circuits obviously rely on diodes for their operation. Diodes are devices that only pass current in one direction. When Ambrose Fleming invented the first diode – a...

Light Emitting Diode

A “Light Emitting Diode” or LED as it is more commonly called, is basically just a specialised type of PN junction diode, made from a very thin layer of...

Transition and Diffusion capacitance

Transition capacitances: 1. When P-N junction is reverse biased the depletion region act as an insulator or as a dielectric medium and the p-type an N-type region have low...
