Integrated circuit, chip and IC refer to integrated circuit, a micro electronic device or component.
The semiconductor manufacturing process is adopted to interconnect the transistors, diodes, resistors, capacitors, inductors and other components and wiring required in a circuit, make them on a small or several small semiconductor chips or dielectric substrates, and then package them in a tube shell to become a micro structure integrated circuit design system with the required circuit functions The process of converting logic and performance design requirements into specific layout physical data. Integrated circuit layout design is also known as layout design. A working step in the integrated circuit design process is to convert the connected netlist into the layout connection graphics required by wafer manufacturers for processing and production. Analog chip refers to analog IC, The integrated circuit chip that processes continuous analog signals is called analog chip. Analog signal refers to the electrical signal formed by using electrical parameters, such as the value of current and voltage, to simulate other natural quantities. The analog signal usually appears as a continuous signal within a given range. Analog chip can be used as the interface between people and equipment and enable people to interact with equipment.
