摘要：
A low cost integrated transceiver for mobile UHF passive RFID reader applications is implemented in a 0.18-μm CMOS process.The transceiver contains an OOK modulator and a power amplifier in the transmitter chain,an IQ direct-down converter,variable-gain amplifiers,channel-select filters and a 10-bit ADC in the receiver chain.The measured output P1dB power of the transmitter is 17.6 dBm and the measured receiver sensitivity is-70 dBm.The on-chip integer N synthesizer achieves a frequency resolution of 200 kHz with a phase noise of-104 dBc/Hz at 100 kHz frequency offset and-120.83 dBc/Hz at 1 MHz frequency offset.The transmitter,the receiver and the frequency synthesizer consume 201.34,25.3 and 54 mW,respectively.The chip has a die area of 4×2.5 mm2 including pads.
