Abstract :
This paper presents an RFID system with fully integrated transponder. The transmit path of the reader as well as key blocks of the tag is designed and fabricated in standard CMOS 0.18 mum process. The system operates at 900 MHz with the coverage range of more than 0.4 cm. The tag´s antenna is integrated on chip without using any special process. The reader employs a coil switching technique to increase its coverage area. The PA in the transmit path of the reader is designed using digital to RF configuration. By employing a proper output network, the PA can deliver a current of 225 mA (RMS) to the reader´s coil.
