Integrated Circuit

I. Introduction

Each body part serves its very own purpose. Pair of eyes is for seeing, pair of ears is for hearing, one tongue is for tasting and many other parts. But try to imagine, can your pair of eyes alone understands what itsees? Or let’s try to reverse my question. Can you understand the happening in the environment if your pair of eyes is not functioning? Maybe for some instances you will but it will be difficult for sure. All information that are being sent by your senses are used and analyzed in our brain. In other words, our brain will summarize all the information before we can decide what will be our response. This is now the highlight of this paper where the same manner is applied in electronics.

At last! We come up to this part. In our previous lessons, we have acquainted ourselves with the different electrical components namely resistor, capacitor and transistor. Each component serves its very unique purpose and if we put them all together, a great function will be made. Integrated circuit is the integration of all the electrical components to serve one goal functioning as one.

II. Definition

Integrated circuit or also known as IC is a type of circuit containing millions of resistors, capacitors and transistors. It is a circuit itself but it must still be placed in a circuit to function. Best example of an IC is a microchip. The brilliant persons behind this amazing integration are Robert Noyce and Jack Kilby.

IV. Types

1. Analog or Linear Integrated circuit

For a continuous output signals, this type of IC is the answer. This is considered as more useful than the other type of IC. It is manufactured as less expensive chips but still been useful for more than 40 years. This is the type of IC in most types of amplifiers. This is preferable to use if we desire to have variation of signal outputs of audio-frequency and radio-frequency.

2. Digital Integrated circuit

As the opposite of the first type, this type does not give continuous output signals. This will only operate at certain states where its building blocks are logic gates since there are only two signals of it, either 1 or 0.
