Abstract :
This paper presents an ASIC design and implementation of digital baseband system for UHF RFID reader supporting the ISO18000-6C protocol. The digital baseband consists of five parts: digital baseband receiver, digital baseband transmitter, controller, CRC (Cyclic Redundancy Check) and serial interface modules. We present a new more secure and effective encode algorithm, TPP (Truncated Pulse Position encoding), which develops from PIE (Pulse Interval Encoding). In addition, we improve the signal adjuster of the digital baseband receiver and transmitter for decoding and encoding more exactly. Under 0.18μm CMOS process, the area of reader digital baseband is 3032802μm2 and the power is 105.215mw.
