Pn Junction : Basic theory

Pn junctions are formed by joining two different type of semiconductor material i.e. p-type semiconductor on one side and n-type semiconductor on another side. In this article, we are going to explain you about p-n juenction formation, phenomena of p-n junction formation and basic equations. Have a look at it. It is discovered by the American physicist Russell Ohl at Bell laboratories. In p-type semiconductor holes are majority carriers and electrons are minority carriers while in n-type semiconductor electrons are majority carriers and holes are minority carriers i.e. one end has the excess of electrons and other has the excess of …

Difference between BJT and FET

BJT and FET both are made up of different semiconductor materials mainly P type and N type. These transistors are basically used for the designing of oscillators, amplifiers, and switches. In our last articles, we explain in detail how to use a transistor as a switch, amplifier and as an oscillator. Here we are going to explain in detail about FET and BJT basics, working and its difference. Bipolar Junction transistor: Bipolar transistor is a three terminal device formed by joining two individual signal diodes back to back, which will give us two PN junctions connected together in series that …

Capacitor Types and its characteristics

When we go to market for purchasing capacitors we got a little bit confused because of availability of different types of capacitors vary in their characteristics and have their pros and cons. Some capacitors can be used in high voltage applications while others used in low voltage applications, some have very low leakage rates and some have high leakage rates etc. Here we provide a list of various types of capacitors, its characteristics behaviour etc. Have a look over it. Types of capacitors (i) Tantalum Capacitor Dielectric material: Tantalum Pentoxide Type: Polarised Characteristics: It offers a very high capacitance level for …
