Integrated circuit (IC) is the most significant technological development of the 21st century if I may say. It has forever transformed the world of electronics. It has reduced the size of electronics from a refrigerator-size to palm-size electronics or even less.


Integrated circuit (IC)

An integrated circuit (IC), sometimes called a chip or microchip, is a semiconductor wafer on which a thousand or millions of tiny resistors, capacitors, and transistors are fabricated. An IC can be a function as an amplifier, oscillator, timer, counter, computer memory, or microprocessor. An exact IC is categorized as either linear (analog) or digital depending on its future application. Integrated circuits distorted all that. The fundamental idea was to obtain a complete circuit, with lots of components and the connections between them, and reconstruct the whole thing in a microscopically tiny form on the surface of a piece of silicon. It was an incredibly clever idea and it has made possible all kinds of “microelectronic” gadgets ranging from digital watches and pocket calculators to Moon-landing rockets and arms with built-in satellite navigation.

IC and Plate

Normally bipolar junction transistors, diodes and field-effect transistors are commonly used electronics components in an electronic circuit. These components are interconnected along with required resistors and capacitors to form an electronic circuit. This type of circuit is known as a discrete circuit as each of the components can be separated from the circuit when required. Nowadays there is a new trend of producing electronic circuits where on a semiconductor wafer numbers of diodes, transistors, and capacitors are permanently fabricated.

As the components in this type of electronic circuit are not separable that is integrated on the semiconductor wafer, this circuit is commonly referred to as an Integrated Circuit. IC is also popularly known as chip or microchip.

Integrated Circuit.

Integrated Circuits are defined as the circuit that comprises elements that are inseparable and interconnected electrically in such a way that the IC cannot be separated for the reason of commerce and construction. Myriad technologies can be used to build such a circuit. Today what we call an IC, was originally known as a monolithic integrated circuit. It is believed that Kilby created the first working IC back in 1958 and he won the Nobel Prize in Physics in 2000 for his hard work. The first buyer for this invention was the US Air Force.

The number of transistors that we have been able to fit into an IC has rapidly increased since their creation, doubling approximately every 2 years. This phenomenon is known as Moore’s Law and is often cited as an explanation for the exponential growth of technology over the last 50 years.

An IC consists of interconnected transistors, capacitors, resistors, diodes, etc. These components are interconnected with an external connecting terminal contained in a small package.

Below is the classification of different types of ICs basis on their chip size.

  • SSI: Small scale integration. 3 – 30 gates per chip.
  • MSI: Medium scale integration. 30 – 300 gates per chip.
  • LSI: Large scale integration. 300 – 3,000 gates per chip.
  • VLSI: Very large-scale integration. More than 3,000 gates per chip.

Based on the method or techniques used in manufacturing them, types of ICs can be

  1. Thin and thick film ICs
  2. Monolithic ICs
  3. Hybrid or multichip ICs

Thin and Thick ICs:

In thin or thick film ICs, passive components such as resistors, capacitors are integrated but the diodes and transistors are connected as separate components to form a single and complete circuit. Thin and thick ICs that are produced commercially are merely the combination of integrated and discrete (separate) components.

Thin and Thick ICs:

Thick and thin ICs have similar characteristics, similar appearance except for the method of film deposition. Method of deposition of films distinguished Thin ICs from Thick ICs.

Monolithic ICs

In monolithic ICs, the discrete components, the active and the passive and also the interconnections between then are formed on a silicon chip. The word monolithic is actually derived from two Greek words “mono” meaning one or single and Lithos meaning stone. Thus, a monolithic circuit is a circuit that is built into a single crystal.

Monolithic ICs

Monolithic ICs are the most common types ICs in use today. Its cost of production is cheap and is reliable. Commercially manufactured ICs are used as amplifiers, voltage regulators, in AM receivers, and in computer circuits. However, despite all these advantages and vast fields of application of monolithic ICs, it has limitations. The insulation between the components of monolithic ICs is poor. It also has a low power rating; fabrication of insulators is not that possible and so many other factors.

Hybrid or Multi-chip ICs

As the name implies, “Multi”, more than one individual chip is interconnected. The active components that are contained in this kind of ICs are diffused transistors or diodes. The passive components are the diffused resistors or capacitors on a single chip.

Hybrid or Multi-chip ICs

These components are connected by metalized patterns. Hybrid ICs are widely used for high power-amplifier applications from 5W to more than 50W. Its performance is better than that of monolithic ICs.

Digital Integrated Circuits

Digital Integrated Circuits

The logic Gates, such as AND gate, OR gate, NAND gate, XOR gate, flip flops, counters; microprocessors are some well-known examples of digital ICs. This kind of IC has two defined levels:1’s and 0’s which implies that they work on binary mathematics wherein 1 stands for on and 0 stands for off. Such ICs are accomplished diligently as they contain more than millions of flip flops, logic gates, and whatnot, all incorporated into a single chip. Examples of digital IC include microcontrollers and microprocessors.

Analog Integrated Circuits

Op-amps, voltage regulators, comparators, timers NE 555, and Sensors are also well-known examples of linear ICs or analog ICs. In this type of ICs, the input and output signals are continuous. The output signal level depends upon the input signal level and the output signal level is a linear function of the input signal level. Linear ICs or analog ICs are most commonly used as audio frequency amplifier and radio frequency amplifier

The analog integrated circuits work by tackling continuous signals and is capable of performing tasks such as filtering, amplification, demodulation, and modulation, etc. Sensors, OP-AMP’s are essentially Analog ICs.

Mixed Signal

When the digital and analog ICs are used on a single chip; the resultant IC is known as mixed-signal integrated circuits.

  • Data Acquisition ICs (including A/D converters, D/A converter, digital potentiometers)
  • Clock/timing ICs

Uses of Integrated Circuits

The integrated circuit uses a semiconductor material (read chips) as the working table and frequently silicon is selected for the task. Afterward, electrical components such as diodes, transistors, and resistors, etc. are added to this chip in minimized form. Electrical components are joined together in such a way that they are able to carry out multiple tasks and calculations. The silicon is known as a wafer in this assembly.

An amplifier is used to raise the amplitude of a signal waveform, without altering other specifications of the waveform such as frequency or waveform. They are one of the most commonly utilized circuits in electronics as well as carry out a range of features in several digital systems.

Amplifiers are used to increase the amplitude of a voltage or current or to increase the amount of power available generally from an AC signal.

Whatever the task, there are three categories of amplifier that relate to the properties of their output;

  1. Voltage amplifiers.
  2. Current amplifiers.
  3. Power amplifiers.

The function of a voltage amplifier is to make the amplitude of the output voltage waveform greater than that of the input voltage waveform (although the amplitude of the output current may be greater or smaller than that of the input current, this adjustment is lesser for the amplifier’s designed objective ).

The objective of a current amplifier is to make the amplitude of the output current waveform above that of the input current waveform (although the amplitude of the output voltage may be greater or smaller than that of the input voltage, this adjustment is lesser for the amplifier´s designed function)

In a power amplifier, the item of voltage and also current (i.e., power = voltage x current) at the output is above the product of voltage x current at the input. Keep in mind that either voltage or current may be less at the output than at the input. It is the item of both that is substantially increased.

Drivers IC

In electronic devices, a driver is a circuit or part made use of to regulate another circuit or part, such as a high-power transistor, liquid crystal screen (LCD), as well as many others.

They are generally utilized to regulate the current flowing via a circuit or to control other variables such as other elements, some devices in the circuit. The term is frequently utilized, as an example, for a specialized integrated circuit that controls high-power switches in switched-mode power converters. An amplifier can additionally be thought about a driver for loudspeakers or a voltage regulator that maintains a connected part operating within a broad variety of input voltages.

Memory IC

Memory technology has no impact on the logical procedure of a tool. Because of the various processing actions called for, some electrical characteristics (EC) might range devices with the same attribute set/pinout but with different memory innovations. An instance is that the VIL (Input Low Voltage) might have some distinction between typical EPROM gadgets. Also, each gadget has a selection of frequency ranges and also packaging options relying on the application and also manufacturing demands. When going over the performance of the device, the memory innovation, and the voltage range do not matter. The major programmable memory types are PROM, EPROM, EEPROM, ROM, and also Flash-type memory. NAND, eMMC as well as UFS gadgets are utilized where high memory density is required


Power management IC

Power management integrated circuits (power management ICs or PMICs or PMU as units) are integrated circuits for power management. Although PMIC refers to a wide range of chips (or components in system-on-a-chip devices), a lot of includes a number of DC/DC converters or their control component. A PMIC is typically included in battery-operated devices such as mobile phones and portable media players to decrease the quantity of space needed.

The term PMIC refers to a class of integrated circuits that perform various functions related to power requirements. A PMIC may have one or more of the following functions:

  • DC to DC conversion
  • Battery charging
  • Power-source selection
  • Voltage scaling
