- Abstract
A reconfigurable architecture is presented to be compatible with conventional passive operating mode and active mode for ultrahigh frequency (UHF) and radio-frequency identification (RFID) tag. The transceiver with frequency locked on-chip oscillator is proposed to increase the read range of RFID system and the lifetime of tag. The transceiver is fabricated in 0.18 μ m standard CMOS process with the active area of 0.246 mm2. For passive mode, the sensitivity of tag is − 1 7 dBm. For the active mode, the sensitivity is − 3 2 dBm only consuming 1.2 μ W under the supply voltage of 0.8 V. The output power is − 1 0 dBm for active transmitting mode and the power consumption is 450 μ W under the supply voltage of 1 V.
