A 90nm CMOS 13.56MHz NFC transceiver
This paper presents the design of a 90nm 13.56MHz NFC Transceiver. The concept of Near Field Communication is introduced while discussing how a combination of both Initiator and Target functions are required. The Initiator circuitry used to generate the required magnetic field and demodulate the received back-scatter is explained and the passive and active Target circuitry used to receive a magnetic field whilst demodulating and load-modulating is presented. Finally there is a short description of the Evaluation Module (EVM) containing the 90nm NFC, an antenna and interface to a host processor or PC.
