摘要
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 mu m standard CMOS process with the active area of 0.246mm(2). For passive mode, the sensitivity of tag is -17dBm. For the active mode, the sensitivity is -32dBm only consuming 1.2 mu W under the supply voltage of 0.8V. The output power is -10dBm for active transmitting mode and the power consumption is 450 mu W under the supply voltage of 1V.
