Special Section on Analog Circuits and Related SoC Integration Technologies

System-on-a-Chip LSIs (SoCs) have been widely used for many applications which include not only the field related to electronics but also new fields like architecture, agriculture, medicine and so on. Scale of such the LSIs has been more increasing for realizing multi-function and complex systems. Although the progress of the process technologies offers a lot of advantages over digital circuits, it has become more difficult to design analog circuits due to the limited supply voltage, power consumption and so on.
