A 1.8V CMOS Direct Conversion Receiver for a 900MHz RFID Reader Chip
-
Abstract
A direct conversion receiver with optimized tolerance to local carrier interference is designed and implemented in a 0.18μm 1P6M mixed-signal CMOS process for a 900MHz RFID reader transceiver.A baseband amplifier with series feedback topology is proposed to achieve passive mixer buffering,baseband DC cancellation,and signal amplification simultaneously.The receiver has a measured input 1dB compression point of -4dBm and a sensitivity of -70dBm when 10dB SNR for digital demodulation is required.The receiver is integrated in a reader transceiver chip and consumes 90mA from a 1.8V supply.-
