Smart grid means an intelligent power network. It is the system that an integrated control center of a power company and sensors of power plants, transmission towers, telegraph poles, or home electronics bilaterally exchanges real-time information to allow customers to use power during an optimized time which enables the most efficient production and consumption of power; it is also a study that information technology (IT) is grafted on the current power grids.

The smart grid system, which is considered as the area that will grow quickly and largely in the next generation’s eco-friendly technology market, enables to reduce electricity use by 10% and wasting of power. Along with commercialization of renewable energy, it will help to ease global warming issues.

Smart grids are not only expected to allow efficient use of electricity but also to create jobs for building infrastructures and other related industries. In addition, related industries will build new areas that use the advantages of the new technology such as home networking equipment, software programs and online services for communicating with home electronics. By connecting the intelligent power network and control system, the laboratory conducts the study in electric vehicles, activation of new and renewable energy, and other studies needed in the next generation’s eco-friendly technology market.

Application-specific integrated circuits (ASICs) are applied not only to memory semiconductors but also to non-memory semiconductor IC that handles voice, image, and data signals such as communication equipment like IMT-2000, medical image machine, home electronics like camcorder and HDTV, industrial electronics like automobile industry, radar, satellite broadcasting. They are also applied to CCD/IR signal sensing system, and memory and non-memory semiconductor integrated chips. The laboratory interprets and analyzes hybrid mode circuits used in chip interfaces for transforming signals between analog users and digital systems that also have analog and high concentration digital circuit blocks such as high-functional amplifiers and reference circuits. The designed chips at the laboratory are used in various application circuits, actual products and systems after going through the process of layout, production, measurement, and capability test. They are also connected to new business projects with such companies like venture enterprises by using library/IP.

Microprocessor, communication systems, and digital signal processing systems require various functions and fast speed. In order to realize the circuits that meet the requirements, many designs of related circuits including PLL, mixer, multiplier, and modulator are needed.
