Abstract: Abstract: 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.
