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

Abstract

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 1.7/1.3/0.8/1.0mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> , respectively. The measured WiFi 11g 54Mbps RX sensitivity is -78dBm and Pout is 20dBm with EVM of -28dB. The measured BT GMSK RX sensitivity is -94dBm and Pout is 10dBm. FM sensitivity is -110dBm and GPS cold/hot-start TTFF sensitivity is -148/-163dBm.
