Abstract

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 P_1dB and >;4dBm TX power (without external PAs) for all bands and RX sensitivity down to -72dBm for UHF band in the presence of transmitter carrier leakage. Implemented in a 90nm CMOS process, the reader occupies 3.6×3.8mm² and consumes less than 114mW from 1.2V/3.3V supply.
