Abstract
A radio frequency integrated circuit (RFIC) device includes: a first RF input/output (I/O) terminal; a second RF I/O terminal, where the first and the second RF I/O terminals are configured to transmit or receive an RF signal; a capacitor coupled between the first and the second RF I/O terminals; a first coil coupled between the first and the second RF I/O terminals, where the first coil is configured to provide ESD protection to the capacitor during a first ESD event; and a fast transient ESD protection circuit coupled between the first and the second RF I/O terminals, where the fast transient ESD protection circuit is configured to provide ESD protection to the capacitor during a second ESD event different from the first ESD event, where a first rise time of the first ESD event is longer than a second rise time of the second ESD event.
