A 60nm WiFi/BT/GPS/FM combo connectivity SOC with integrated power amplifiers, virtual SP3T switch, and merged WiFi-BT transceiver

A highly integrated WiFi/BT/FM/GPS connectivity combo SOC is implemented in a 60nm CMOS process. This work presents the proposed WiFi/BT merged RF transceiver, a virtual SP3T switch, and DPD algorithm to save chip area, reduce BOM and enhance performance simultaneously. The WiFi/BT/FM/GPS RF transceiver areas are l.7/l.3/0.8/l.0mm
