Abstract

A highly integrated 2.4GHz wireless communications platform for an Active RFID system supporting perpetual operation in indoor lighting conditions is presented. The system requires no external components except an antenna, two BAW resonators, a small solar panel, and a rechargeable battery. It is implemented in 65nm CMOS, comprising of a BAW-based transceiver, digital baseband and integrated power management unit. Including converter losses, the system consumes 850nW when idle, 155μW in receive mode, and 4.7mW in transmit mode.
