A multi-band multi-standard RFID reader SoC is described in this paper. It can be software-reconfigured to support mostly used protocols in UHF, 2.45GHz and 13.56MHz frequency bands. The single-chip reader integrates a RF transceiver, a synthesizer, ADCs/DACs and a digital baseband modem. It achieves >;0dBm RX P1dB and >;4dBm TX power (without external PAs) for all bands and RX sensitivity down...
A fully integrated 2.4 GHz transceiver based on the IEEE802.15.4 specification has been designed using a 130 nm CMOS technology. Concurrent system and design optimizations were required to reach an energy efficiency of 21.5 nJ/bit in RX mode and 32.5 nJ/bit in TX modes, respectively, at a data rate of 250 kbit/s. The circuit includes a -5 dBm transmitter, a -81 dBm sensitivity receiver, an integer...
