MEMS-based Reconfigurable CMOS LNAs for Wireless Applications

摘要

This study investigated on the requirements of covering multiple standards in portable wireless devices. A comparison in terms of system and circuit performance between the wideband devices and narrow-band reconfigurable devices was presented. Also, these devices were compared in terms of physical specifications such as area and number of pins. To overcome the limitations of Radio Frequency (RF) components and to optimize their RF performance, available RF microelectromechanical systems (MEMS) components with feasibility of integration with RF Complementary Metal-Oxide Semiconductor (CMOS) circuits were discussed. Finally, the study results on pros and cons of CMOS-MEMS integration.
