Transistor vs Integrated Circuit: What's the Difference?

Integrated circuits and transistors are both essential components in electronic devices. They are the small pieces that make up the big picture of electronics. Although both integrated circuits and transistors serve the same general purpose, they each have unique functions within an electronic circuit.

Integrated circuits and transistors can even be combined to create a single device. Integrated circuits and transistors are used in various electronics from computers to cellphones, automobiles, thermostats, and almost any piece of technology that you can think of.

These two component types are fairly simple but pack a big punch when combined correctly for different uses.

This article explains the differences between integrated circuits and transistors so you can know what is best for your project needs.

Definition: What is Integrated circuit? What is transistor?

An integrated circuit (IC) is an electronic circuit that has been manufactured and embedded onto a single chip. They are made of multiple transistors and other discrete components (capacitors, resistors, diodes, etc.) all packaged together. ICs are the small black chips that you find in any piece of technology that requires an electronic circuit.

A transistor is a semiconductor device that is used in electronics. It is an electro-mechanical device that can be used either as an amplifier or a switch. The transistor is one of the most important pieces of technology in modern electronics. It is a tiny device that is typically found etched onto a silicon “chip” that can be attached to other circuit boards, wires, and other electronic devices. Integrated circuits and transistors are both essential components in electronic devices.

Transistor vs Integrated Circuit: What’s the Difference?

Size: Integrated circuits vs transistors

The size of an integrated circuit is usually measured in terms of its length and width, whereas transistor dimensions are given in terms of length and diameter.

There can be quite a large discrepancy in the sizes of ICs, as they come in many different varieties and packages. In terms of height, they are usually in the order of just a few millimeters.

I have existed in a huge variety of sizes and formats since the first ICs were developed. The smallest ICs are now microscopic, either as nanoscale single-chip ICs or as “micro dice” (very small dice).

The smallest discrete transistor types are now also microscopic, with MOSFETs and IGBTs now being made using a standard process for making computer chips. However, there remain large discrepancies in the sizes of discrete transistors.

Composition: Integrated circuits vs transistors

ICs are made from many different types of semiconductor materials, such as silicon, germanium, silicon germanium, silicon carbide, gallium arsenide, etc. Transistors are normally made from silicon semiconductor materials. However, some transistors are also made from germanium semiconductor materials. The choice of semiconductor material affects the properties of the transistor.

Also, still, on the aspect of composition, it is clear that integrated circuits have numerous electronic components such as transistors, capacitors, and inductors stacked together to form a single chip. Transistors, on the other hand, don’t have numerous components.

Price: Integrated circuits vs transistors

Integrated circuits are much more expensive than transistors. This is mainly because they are more complex to manufacture than transistors.

As we have seen, ICs have complex designs and structures. That means that to manufacture one, we have to consider many different aspects of production.

On the other hand, transistors are made from silicon semiconductor materials that are easy and cheap to process.

As mentioned earlier, the choice of semiconductor material and the manufacturing process also affect the price of the transistor. Transistor prices are set by the market, regardless of the manufacturer.

However, IC manufacturers set their own prices for their ICs and usually set their prices based on the components and processes used. Electronics engineers should carefully select the right type of transistor for their application and the manufacturer. This will help them save money on their project.

Applications: Integrated circuits vs transistors

The main difference between integrated circuits and transistors is the amount of functionality they can provide.

Integrated circuits have many components built into one chip, whereas transistors are just one component.

ICs have many uses, such as in digital circuits, analog circuits, and even in power circuits. They can be used in oscillators, timers, shift registers, and a variety of other circuits.

Transistors, on the other hand, can be used for amplifying low-current signals, switching high-current signals, or switching low-current signals. They can also be used as an oscillator in some cases.

Transistors can be used in digital circuits, but they are mainly used in analog circuits and power circuits. Some transistors are designed specifically for high-power applications.

How many transistors are in integrated circuits?

The number of transistors used in a circuit depends on the circuit design. However, it can range from a couple of transistors to thousands of transistors. With integrated circuits, it depends on the type of IC. For example, an op amp IC can have just a few transistors while a microprocessor IC can have thousands of transistors.

Also, the number of transistors in an IC will also depend on the exact application of the IC.

IC manufacturers usually specify the numbers and even the type of transistors that are in a single IC.

How to choose a reputable IC and transistor supplier in China

Where you buy your IC and transistor matters. Like any other sensitive electronic component, ensure that you buy from a reputable source: This means a supplier or distributor who has a good reputation when it comes to electronic components
