A Circuit Component

Introduction to Circuit Component

An electronic circuit is composed of individual components which are electronic such as resistors, transistors, capacitors and the inductors and diodes connected by wires which are conductive or traces through which current or the electric current can flow. 

In an integrated circuit or we can say IC the components and interconnections are formed on the substances which are the same. Typically a semiconductor such as silicon doped less commonly the gallium arsenide.

A circuit which is electronic can be usually categorized as analogue. The most widely used semiconductor in electronic circuits is the MOSFET transistor which is a metal-oxide-semiconductor.

Component of an Electric Circuit 

The analogue electronic circuit is the one in which voltage or current may vary continuously with time which corresponds to the information that is being represented. The circuit is constructed from two building fundamental blocks: parallel or the series circuits.

In a series circuit, the same current passes through a series of components. A Christmas string light is a good example of a series circuit.

In a circuit which is parallel, all the components are connected to the same voltage and the current divides is between the various components that are according to their resistance. 

The basic components of analogue circuits are wires and resistors and the capacitors, diodes, inductors and the transistors. These type of circuit is represented in the schematic in which wires are shown as lines and each component that we have discussed has a unique symbol. Analog circuit analysis employs the law of the Kirchhoff's circuit: all the currents that are at a node - a place where wires meet and the voltage that is around a closed loop of wires is 0. Example include a discrete inductor or the resistor. The component which is active such as transistors are often treated as the current which is controlled. A field-effect transistor that can be modelled as a source of current from the source to the drain with the current that is controlled by the gate-source voltage.

Basic Electric Circuits 

In electronic digital circuits, the electric signals that take on waves are discrete values to represent logical and numeric values. These values are represented by the information that is being processed here. The process which is designed for digital circuits is fundamentally different from the process for circuits which are analogue. As a consequence, there are extremely complex circuits which are digital. with billions of elements where logic is integrated on a single silicon chip and can be fabricated at a cost which is low. Such digital circuits which are integrated are ubiquitous in modern electronic devices. Examples include calculators and mobile phones and handsets along with computers. As the digital circuits become more complex there arises the issue of time delay. The logic races that is the power dissipation which is non-ideal switching on-chip and inter-chip loading and the leakage currents limit circuit density performance and the speed.

The digital circuit is used to create general-purpose computing chips for example such as microprocessors. And the custom-designed circuits which are of logic are known as specific application integrated circuits ASICs.
