Abstract
In this work, a batteryless CMOS RF transceiver for WSN nodes is presented. It includes a fully functional receiver for symmetrical RX/TX throughput and exploits narrowband active transmission to improve the uplink reading range without burdening the reader complexity. A PLL-based architecture is adopted both to recover incoming data and synthesize the TX carrier from the input RF signal. This enables crystal-less operation, thus minimizing the system com- plexity and cost.
