Characteristic & Useful Facts About Integrated Circuits


An integrated circuit (IC), a chip, microchip, or microelectronic circuit, is a semiconductor wafer on which thousands or millions of tiny resistors, capacitors, diodes, and transistors are made.

As the name suggests, it is a system of many small, interconnected parts built into a thin semiconductor material layer (usually silicon crystal).


One IC could hold tens of thousands or even millions of Transistors, resistors, capacitors, and diodes.

It may also have other parts connected by a complex web of semiconductor wafers, copper, silicon, and other materials. Each part is small, usually microscopic, in size. The result is a monolithic chip, which is also very small. It usually only takes up a few millimeters or centimeters of space.


What is IC?

The computer processor is a typical example of a modern IC. It usually has millions or billions of transistors, capacitors, logic gates, and other connected parts to make a complex digital circuit. The processor is an integrated circuit, but not all ICs are processors.


What Integrated Circuits Have Changed Over Time


What Integrated Circuits Have Changed Over Time:

The transistor, made up of the words “transfer” and “resistor,” was invented in 1947.

Initially, each transistor came in its plastic package, and each circuit comprised separate transistors, capacitors, and resistors. Due to the size of these parts, early ICs could only fit a few of them on the circuit board, all wired together.

As solid-state electronics improved over time, making parts smaller became easier.

In the late 1950s, Jack Kilby of Texas Instruments, Inc. and Robert Noyce of Fairchild Semiconductor Corporation found ways to put thin metal paths on devices and make them work as wires. When they figured out how to connect small electrical devices, it was the first step toward making the modern IC.


Design and Building of Modern Integrated Circuits:

ICs have come a long way in the last 50 years, with faster speeds, more storage space, and smaller sizes.

ICs today are so much more complicated than they were in the beginning. They can fit billions of transistors and other parts on a small material. Modern ICs are all one piece, with the different parts built right into the silicon crystal instead of being mounted on it.

Multiple levels of abstraction are used in an IC. The IC comprises a thin piece of semiconductor called a wafer. The wafer is fragile and has many complex connections between its many layers. A die is a group of these wafers that work together.


Characteristic Features:

When millions or billions of parts are on a single chip, placing and connecting each part separately is impossible. Die holes are too small to solder and connect to.

Instead, designers use a special-purpose programming language to make small circuit elements and combine them to make the size and number of components on the chip get bigger and bigger as needed by the application.

The ICs are “packaged” to turn the fragile and small die into a black chip that is now used in many devices, such as computers, smartphones, cell phones, cars, planes, amplifiers, network switches, and other electronic devices like toasters, microwaves, washing machines, TVs, etc.


Different Kinds of IC:

ICs can be either linear (analog) or digital, or a mix of the two, depending on their use.

Analog IC:

Analog or linear ICs have outputs that change continuously based on the level of the input signal. In theory, these ICs could be in any number of states. With this type of IC, the level of the signal coming out is proportional to the level of the signal going in. The line should be straight when graphing the instantaneous output against the instantaneous input.

Most analog ICs are very simple and only have a few parts.

Linear IC:

Linear ICs boost the power of audio frequencies (AF) and radio frequencies (RF). In these situations, the operational amplifier (op-amp) is often used. A temperature sensor is another common way that an analog IC is used. Linear ICs can be set up to turn on or off different devices when a signal reaches a specific value. These things are:

Air conditioning, heating, and cooking

Digital IC:

Digital ICs don’t work over a continuous range of signal strengths like analog ICs do. Instead, they only work at a few well-defined levels or states. Digital ICs are made up of logic gates, which work with binary data or signals that can only be in two states: “low” and “high”.

Digital ICs are now being used in more and more situations, such as Computers, business networks, modems, and frequency counters. A mixed IC uses both digital and analog design ideas. It could be used as:

  • digital-to-analog converter
  • analog-to-digital converter clock/timer IC

The ICs and Microprocessors:

The microprocessor is the most complicated kind of IC, which can do billions of things per second. In a computer, a microprocessor holds the central processing unit (CPU), which runs the computer, or the graphics processing unit (GPU), which specializes in rendering images and video.

A single microprocessor has billions of transistors that are all connected. Each transistor has its logic function that is controlled by the clock.


When the state of the clock changes, the logic functions (like calculations) that the transistors are programmed to do happen. The frequency of the clock determines how fast these things happen.


Uses Of Integrated Circuits:

As of 2011, integrated circuits are used in many places because they are better than other kinds of electronic circuits in many ways. They are in every electronic device controlled by a microprocessor, like cell phones, portable music players, gaming systems, personal computers, and other digital devices.

This is because, by the standards of the 21st century, an integrated circuit (IC) or chip is a highly complex device. It can fit millions of electronic parts like transistors, resistors, and capacitors on a few square centimeters of silicon.

However, when the first models were made in 1958 and 1959, there weren’t many ways to use them. This was because they were simple devices that were hard to make in large quantities.



A researcher at Texas Instruments in the United States named Jack Kilby is thought to have been one of the first to see how integrated circuits could be helpful.

In 2000, he won the Nobel Prize in Physics for his work on the electronic circuit, which led to its creation.

German engineers worked on the idea for the IC chip as early as 1949, but Kilby and another US-based scientist named Robert Noyce were the first to get patents for the idea.
