Organic RFID transponder chip with data rate compatible with electronic product coding

摘要

Data rates of plastic transponder chips have been limited to a few kHz, limited by the inherent low mobility of organic semiconductors. However, a target application for plastic RFID tags is Electronic Product Coding (EPC), which will require, at a base carrier frequency f_c = 13.56 MHz, a data rate of f_c/512 = 52.969 kb/s. In this work, we show that the compatibility of organic semiconductors with high-k gate dielectrics allows boosting the current drive of transistors in functional circuits to EPC compatible clock rates. We demonstrate an 8 bit RFID transponder chip with critical dimension of 2 μm having a data rate of 50 kb/s at V_(DD) = 18V.
