Abstract
Disclosed are devices and methods related to a CMOS switch for radio-frequency (RF) applications. In some embodiments, the switch can be configured to include a resistive body-floating circuit to provide improved power handling capability. The switch can further include an electrostatic discharge (ESD) protection circuit disposed relative to the switch to provide ESD protection for the switch. Such a switch can be implemented for different switching applications in wireless devices such as cell phones, including band-selection switching and transmit/receive switching.
