An Integrated Circuit (IC) is a compact semiconductor device that combines multiple electronic components, such as transistors, resistors, and capacitors, onto a single chip. ICs play a vital role in modern electronics by enabling miniaturization, improved performance, and energy efficiency. They are widely used in various applications, including microprocessors, memory devices, amplifiers, and power management systems. ICs are categorized into analog, digital, and mixed-signal types, catering to diverse industries like consumer electronics, telecommunications, medical devices, and industrial automation. By replacing bulky discrete components, ICs have revolutionized technology, making electronic devices smaller, faster, and more reliable.
