What is a Microchip?

A microchip is an integrated circuit that has thousands of small capacitates and resistors. The integrated circuit is made out of semi-conducting material such as germanium or silicon. It is also known referred to as computer chip, microchip, or silicon chip.
A single integrated circuit can have millions of transistors, some of which are as small as 5 millimeter square and 1 millimeter square. There are many electronic components in an integrated circuit such as transistors, resistors, capacitors, diodes, which are organized in such a way that the produce a special effect. The integrated circuits that are out now have about 2 billion transistors.
Each component has its own function, for example, the transistor behaves like an ‘on' or ‘off' switch, the diode enables electricity flow, the resistor control electricity flow and so on. Such circuits can be found in various electronic devices such as computers, mobile phones, satellite navigation systems, airplanes and even traffic lights.
The many types of integrated circuits include analog circuit, digital circuit and mixed circuit. Analog integrated circuits work by processing continuous signals and they are used for purposes such as demodulation, amplification and active filtering. Digital integrated circuits work through a process of binary mathematics. Instead of working through a continuous series of signals, they operate through set levels or states.
The integrate circuits that are used in cell phones are the memory-integrated circuits. They are also used in sound systems and televisions. A computer memory integrated chip can have 20 to 40 memory chips, while the other types have lesser than this.
Earlier discrete circuits were used, but now integrated circuits are preferred because of their lower cost and performance. Since components of the integrated circuit are printed using photolithography, integrated circuits do not cost much to manufacture. As the switching process happens faster and because components are put closer together performance is high.
When you look into integrated circuits according to classification, the various classification forms are Small-scale integration (SSI), Medium-scale integration (MSI), Large-scale integration (LSI), and Very large-scale integration (VLSI).
The most common integrated circuits are the dual-in line type, which has 8, 16, 24 pins. These circuits are easy-to-use and they just have to be inserted into specified slots for usage. However, since they are very delicate, care must be taken in their handling. It is very important to protect them from high temperature and humidity so that they are in good working condition.
