A UHF RFID reader baseband for multi-protocol with universal transmitter

In this paper, a UHF RFID reader baseband for multi-protocol with universal transmitter is present. A universal transmitter is proposed that can support all of the coding method of UHF RFID, except that a MCU of DW8051core and some supported module are included in the chip. It provides flexible choice for users to select coding method and data rate by set the related control registers. The UHF RFID Reader IC is fabricated in 0.18μm CMOS technology. The area of digital part on the right of IC is 4.4mm

. EDA tool Synopsys PrimeTime PX has been exploited for power consumption estimation with post-layout netlist, which shows that the digital baseband consumes an average power of 4.9μW (1.8V) over a succession of receiving a sequence of response. The power will rise up to 220μW (1.8V), when containing the memory part.
