The article provides an overview of integrated circuit ( IC ), covering their definition, historical development, and advantages over earlier technologies like transistors. What is an Integrated Circuit ( IC )? Before the discovery of ICs, the basic method of making circuits was to select the components like diodes, transistors, resistors, inductors and capacitors and connect them by shouldering. But due to size and power consumption issues, it was necessary to develop a small size circuit with less power consumption, reliability and shockproof. After the invention of the semiconductors and transistors, things were quite simplified to a particular extent, but the ... What does IC mean? Integrated Circuit (IC), chip or microchip, is a miniaturized electronic circuit consisting of multiple electronic components interconnected to form a complete electronic function.
