peripherals and IA (information appliances) products. It has become a common perception that slim, mobile, and low power consumption will add its importance to the future product design of personal computer and handheld electronics devices. In view of this trend, they have dedicated substantial resource in the research and development of mixed signal IC design technology aiming for brining future oriented, good performance, and environment-friendly products to the market. And they have gained much achievement in the technology fields such as mixed-mode IC design, embedded/memory logic IC design, and system logic IC design.
