Toward a real system integration; A direction of IC technology

A direction of IC technology is discussed with relation to mixed signal and interconnects technology for realizing real system integration. IC technology has progressed from an integration of simple digital circuits to an integration of increasingly complicated circuits and devices. Mixed signal technology is currently widely used for SoCs to compensate damage of externally received signals. In CMOS RF circuit technology coping with the size of on-chip inductor technology is vital for many SoCs for wireless systems. Millimeter wave communication will realize Giga-bit wireless data transfer and requires interesting new IC technologies such as a transmission line and an on-chip antenna technology. Transmission of electric power to chips will be an important future IC technology for fine-grained power management systems and ubiquitous systems.
