Abstract

The encoder and decoder are the keys of security and error-rate for UHF RFID reader. In this paper, we present a multi-bit encoder and FM0/Miller decoder design which has less error-rate and more security. We take resource reused, no-gap-link between different data areas of encoder, and low power into consideration in our design. FM0/Miller decoder can handle a ± 25% data rate variation and the error-rate is 0. Under TSMC 0.18μm process, the area of encoder is 27685μm² and the power is 253μw. The area of decoder is 53827μm² and the power is 394μw.
