# What is Integrated Circuit and Its Types

## INTRODUCTION

Hey guys, In todayโs blog weโll discuss โwhat is an integrated circuit and its typesโ

In our previous blog โEvolution of computer,โ we saw that the integrated circuit is used in โthe third generation of computerโ. So, In todayโs blog, we are going to discuss โintegrated circuitโ in detail

## INTEGRATED CIRCUIT INVENTORS

The integrated circuit(IC) was invented between 1958 and 1959 by the American electrical engineers โJack Kilbyโ and โRobert Noyceโ(an American physicist). Noyce developed the integrated circuit but the same concept has been invented by Jack Kilby at Texas Instruments in Dallas. Robert Noyce invented the first monolithicย integrated circuitย in 1959. On the other hand, Jack Kilby was invented in 1958 and also he was awarded the Nobel Prize in physics on 10 December 2000.

## INTEGRATED CIRCUIT

An integrated circuit (IC) is a set of electronic circuits on small flat pieces of semiconductor that is normally known as a โSilicon Chipโ and it is also known as a microchip or microelectronic circuit.

Integrated Circuitsย are defined asย the circuitย that comprises elements that are inseparable and interconnected electrically.ย  An IC is an assembly of electronic components, such as Registers, Capacitors, Diodes, and Transistors. They are fabricated as a single unit, In which the transistors and diodes are miniaturized active devices and the capacitors and resistors are passive devices. Since the 1960s the speed, size, and cost of the integrated circuit have been relatively low to the older generations of circuits.

## TYPES OF INTEGRATED CIRCUIT

There are two main types of Integrated circuits:

1. Analog IC
2. Digital IC

An analog integrated circuit is a circuit which is dealing with signals free to vary from zero to power supply, It means that the analog circuit is connected to those devices that collect signals from the environment and send them back to the environment. e.g. a microphone converts fluctuating vocal sounds into an electrical signal of varying voltage.

In simple words, analog means that signal which is in continuously varying voltage is known as analog ICs. In this type of IC, the input and the output signal both are continuous in nature.

Examples of analog integrated circuits are operational amplifiers, differential amplifiers, voltage regulators, modulators, power management circuits, etc.

### 2. Digital Integrated circuit

On the other hand, a Digital circuit is a circuit that is embedded with many other logic circuits programmed to perform some logical operations. There are some logic operations that are NOT gate, OR gate, and AND gate which combine to carry the specific operation. This IC operates with the binary numbers 0 & 1. 0 indicates the 0 V and 1 indicates the +5V

In simple words, A digital IC that operates a few levels of operating signal amplitude is known as a digital IC. And, these are designed by using multiple numbers digital logic gates, NOT gates, OR gates, AND gates, etc. The digital gates work with binary numbers 0 & 1.

Examples of Digital logic IC are Half adder, full adder, multiplexer, demultiplexer, code converter, etc.

• Integrated circuits are smaller than discrete circuits.
• It consumes less energy and the weight of an IC is less than the discrete circuit.
• It is more reliable.
• IC has the ability to control the extreme level of temperatures.
• It increases the Operating speed.
• Suitable for small signal operation.

• In IC the power dissipation is limited to 10 watts.
• IC can handle the limited amount of power
• Voltage depends on capacitors and the transistors.
• A low-temperature coefficient is difficult to achieve.
• Indicators or Coil can not be fabricated.
• P-N-P assembly is not possible.
• The operation can be performed in low voltage and the IC function can be Performed at fairly low voltage
