Electronic devices have become mature and been diversified, and flexibility is becoming increasingly important in integrated circuits. Circuits have obtained flexibility and reconfigurability at various levels due to digitization, i.e. simplification, but real-world interfaces such as external communications and sensors intrinsically require analog circuits rather than digital. Digital signals can be processed by PCs, DSPs, FPGAs, custom LSIs, and other digital circuits. In analog circuits, however, general-purpose products offer only a limited and fixed range of functions. The development of reconfigurable analog RF circuits will provide a means of breaking through this impasse and realize both flexibility and high performance. Here we provide a forward-looking perspective on reconfigurable analog RF circuit technology; in particular it s present and future key components, and describes the pathway for innovation and change.
Abstract
Electronic devices have become mature and been diversified, and flexibility is becoming increasingly important in integrated circuits.

Digital signals can be processed by PCs, DSPs, FPGAs, custom LSIs, and other digital circuits. In analog circuits, however, general-purpose products offer only a limited and fixed range of functions. The development of reconfigurable analog RF circuits will provide a means of breaking through this impasse and realize both flexibility and high performance.
