Definition: An oscillator is basically a signal generator that produces a sinusoidal or non-sinusoidal signal of some particular frequency. Oscillators find their various applications as these are the fundamental component of any electrical and electronic circuits. Continuous oscillations are the basis of working of an oscillator. Sometimes, an oscillator is said to be an amplifier …
Both intrinsic and extrinsic semiconductor is the 2 categorizations of semiconductor material. The difference between intrinsic and extrinsic semiconductor is that Intrinsic semiconductors are the pure form of semiconductor materials. Whereas extrinsic semiconductors are impure semiconductor formed by adding an impurity to a pure semiconductor. No, any external impurity is doped in case of an …

Definition: A Schottky diode is a 2 terminal metal-semiconductor device that is formed by diffusing an n-type semiconductor over a metal. Both metal and n-type semiconductor have electrons as their majority carriers, as almost negligible holes are present in a metal. As in Schottky diode, only majority charge carrier i.e., electrons are responsible for conduction. …
Definition: LCD is an acronym used for Liquid Crystal Display. It is basically a display technique in which liquid crystals are used in order to produce an image on the screen. Unlike an LED, an LCD does not hold the property of producing light. However, it allows some regions to appear either bright or dark …
Definition: JFET is the shortened form for Junction Field Effect Transistor. It is a 3 terminal semiconductor device in which current conduction takes place only due to the flow of majority charge carriers. Thus, it is a unipolar transistor. The 3 terminals of the JFET are source, drain and gate. Unlike BJT, JFET is a …
Definition: Analog and digital communications are the two types of data transmission system however several factors generate the difference between the two. The major difference between analog and digital communication lies in the signal being transmitted. In analog communication, the message signal is in analog form i.e., continuous time signal. As against in digital communication, …

Definition: A PNP transistor is an acronym used for a positive-negative-positive transistor. It a mainly a classification of bipolar junction transistor and is a three terminal device consisting of the emitter, base and collector. Here, majority charge carriers are holes and hence they are responsible for the flow of current through the device. In PNP …
Definition: A number system that corresponds only two numerical digits i.e., 0 and 1 is known as a binary number system. As it is a 2-digit system thus known as a base 2 system. The operation of a computer system solely relies on the binary number system. As it only understands binary values i.e., 0 …
Definition: Photovoltaic cells are basically those semiconductor devices that show sensitivity towards light. It has the ability to change radiation energy into equivalent electrical energy. The name of the device itself shows its operation. As the word photo is used for light and voltaic is used for electricity. Photovoltaic cells are also known as solar cells as …
Both p-type and n-type semiconductor is the classification of extrinsic semiconductors. The major factor that generates a difference between p-type and n-type semiconductor lies in their doping material. A p-type semiconductor material is formed by the addition of group III elements or we can say trivalent impurity to a pure (intrinsic) semiconductor. On the contrary, …
