Construction of silicon controller rectifier (SCR)

The basic construction of silicon controlled rectifier (SCR) is shown in above fig. It is made up of silicon and its operation as a rectifier can be controlled, hence the name given as silicon controlled rectifier. The

Construction of N-channel junction field effect transistor (JFET)

The construction of junction field effect transistor (JFET) is shown in above figure. The junction field effect transistor (JFET) in which the electrons as majority charge carriers due to this only current conduction takes place is known

Difference between intrinsic and extrinsic semiconductor

Difference between intrinsic semiconductor and extrinsic semiconductor Intrinsic semiconductor Extrinsic semiconductor The intrinsic semiconductor is extremely pure semiconductor. The extrinsic semiconductor is impure semiconductor. Electrical conductivity of intrinsic semiconductors is poor. The electrical conductivity of extrinsic semiconductor


What is a semiconductor? The semiconductors are the type of material which electrical property lies between conductor and insulator. Semiconductors act like insulator at very low temperature, as the temperature increases conduction of semiconductor increases. Semiconductors in

Advantage of semiconductor diode over vaccum tubes

Advantage of semiconductor diode over vaccum tubes The semiconductor diode has very small interelectrode capacitances. This is very important in high frequency application. The semiconductor diode does not produce any current in the absence of applied voltage.

Difference between Monolithic ICs and Hybrid ICs (integrated circuits)

Following are the difference between monolithic ic and hybrid ic. Monolithic ICs Hybrid ICs Monolithic integrated circuits which are  fabricated entirely on a  single chips. Hybrid integrated circuits are  fabricated by inter-  connecting a number of  individual chips. A
