An Integrated Circuit (IC) also called as a microchip or chip. It shows a combination of many tiny resistors, transistors and capacitors. An IC can offer various functions: amplifier, timer, counter, oscillator, microprocessor or computer memory. It provides several advantages, such as smaller size, lesser weight, high reliability and reduced cost. Also, integrated circuits have low power requirement, and easily replaced. With the mass production method, the price is reduced. The ICs are more reliable, offer increased operating speed and efficiency. They are appropriate for small signal procedure. Further, there are low supply voltages.
