Abstract :
This paper presents the design of a 90 nm 13.56 MHz 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 90 nm NFC, an antenna and interface to a host processor or PC.
