Integrated Circuit

An integrated circuit (IC) is a chip or microchip that consists of a substrate created from semiconductor material and thousands or millions of tiny electronic components installed on it. It is a complex fast-speed device with great capacity and small sizes. Its components are extremely little and the size of an entire chip is from a few square millimeters to a few square centimeters. It is the invention of the transistors in 1947 by William B. Shockley that became a base for integrated circuits.

Usually, the substrate is produced from silicon crystal, and in most modern ICs, the components are embedded into it. The electronic components are microscopic active devices like transistors and diodes, and passive devices like capacitors and resistors. The components are interconnected through a complex web of semiconductor wafers from copper, silicon, or other material that function as wires. A single semiconductor substrate is quite fragile, therefore a combination of substrates installed one on the another is often used.

Integrated circuits are used in almost every modern electronic equipment including computers, mobile phones, smartphones, televisions, radars, video processors, audio amplifiers, logic devices, toys, and other electronic devices and appliances like washing machines, toasters, microwaves, televisions, etc. They can function as amplifiers, microprocessors, microcontrollers, counters, timers, logic gates, oscillators, voltage regulators, radiofrequency decoders and encoders, memory devices, etc.

The integrated circuits differ in size, number of components per chip and their arrangement, and used technologies. There are three types of ICs: digital integrated circuits, analog integrated circuits, and mixed integrated circuits.

  • Digital integrated circuits are widely used in microprocessors, digital signal processors, computers, memory chips, and frequency counters. They operate with digital input and binary input data like 0 and 1. The programmable ICs, logic OCs, power management integrated circuits, and interface ICs also refer to this category.
  • Analog or linear integrated circuits include radio frequency integrated circuits, linear integrated circuits, and operational amplifiers that are the most frequently used. Analog integrated circuits have high voltage gain and fewer transistors in comparison to digital integrated circuits. Analog ICs are often used as audio-frequency and radio-frequency amplifiers, temperature sensor in heaters, ovens, air conditioners, switches to turn on / off devices.
  • Mixed integrated circuits combine digital, RF, and analog integrated circuits on one chip. They operate as analog to digital converters, digital to analog converters, and timing/clock ICs.

There are also used logic gates integrated circuits, switching integrated circuits, timer integrated circuits, and amplifier integrated circuits. The most complicated type of IC is a microprocessor. It includes billions of interconnected transistors and performs billions of operations and logic functions per second. It contains the CPU running a computer or the GPU used to render images and video.

Electrical Diagram Software →

Beginning from the 19th century, people tried to tame electricity. Nowadays, electrical engineering covers a wide range of applications starting from providing illumination in our homes to developing space technologies. Considering the fact that every project needs documentation, engineers use electrical diagram software to develop these projects. Standard electrical symbols of electrical components are recognizable all around the world. This illustration represents the 26 libraries that are supplied by the ConceptDraw Electrical Engineering solution. The Electric Engineering libraries contains about a thousand objects enabling you to draw various charts depicting electrical connections and circuits, along with schemes of different equipment and devices. The electric engineering libraries delivered with ConceptDraw solution meet the standards adopted in the image to electrical circuits. So they can be used by professionals along with amateurs in electrical engineering.Electrical Diagram Software *

Electrical Symbols — Analog and Digital Logic →

Digital electronics or digital (electronic) circuits are electronics that handle digital signals – discrete bands of analog levels – rather than by continuous ranges (as used in analogue electronics). All levels within a band of values represent the same numeric value. Because of this discretization, relatively small changes to the analog signal levels due to manufacturing tolerance, signal attenuation or parasitic noise do not leave the discrete envelope, and as a result are ignored by signal state sensing circuitry. 26 libraries of the Electrical Engineering Solution of ConceptDraw DIAGRAM make your electrical diagramming simple, efficient, and effective. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram.Electrical Symbols — Analog and Digital Logic *

Interior Design. Site Plan — Design Elements →

Aside from decorating inner spaces, which is a realm of interior design, the art of exterior design is about home facades, playgrounds and yards. To start a project, first of all, you need a site plan of the place, and a list of customers’ requirements. With special software you can do a plan of any place like parking, interchange or driveway easily. There is one of the three libraries supplied with ConceptDraw Site Plans solution. It is designed to draw planning areas adjacent to buildings. For example parking, exit road or house territory for rest. This kind of building plans can be used for providing parking control that helps to organize traffic near residential areas. The well considered road planning will improve safety and will help to manage the number of vehicles near buildings. The ConceptDraw library "Parking and Roads" includes vector graphic images of parking spaces, lots and strips as well as street junctions, driveways and interchanges.Interior Design.

Network Glossary Definition →

When talking about engineering, one should define all the terms used, so anybody could understand the topic. Typical network glossary contains definitions of numerous network appliances, types of networks and cable systems. The understanding of basic is crucial for server management, network administration and investigating problems. The network glossary defines terms related to networking and communications. The most of glossary items has their visual representation in ConceptDraw DIAGRAM libraries of the Computer Network Diagrams solution. This illustration presents a local area network (LAN) diagram. It designed to show the way the interaction of network devices in a local network. The diagram uses a library containing symbols of network equipment, connections and the end-point devices such as network printer, hubs, server, modem and finally computers (PC, mac, laptop).
