Integrated Circuits (ICs) are semiconductor devices that combine multiple electronic functions into a single chip, enabling complex circuit behavior within a compact and highly integrated form. They serve as fundamental building blocks in modern electronic systems by providing standardized, repeatable electrical functionality.
This category broadly includes ICs designed for:
ICs may be implemented using analog, digital, or mixed-signal design approaches, and are commonly categorized by their primary function and intended electrical role within a circuit.
