Abstract :
Low temperature polycrystalline silicon (LTPS) thin film transistor (TFT) is an emerging technology to manufacture active matrix liquid crystal displays (AMLCDs). With its maximum frequency of oscillation fmax reaching beyond 1 GHz, it becomes feasible to develop integrated circuits in LTPS TFT technology to facilitate system on panel or system on display. This paper investigates the LTPS TFT characteristics for developing RFID tags. An equivalent circuit model was proposed for LTPS TFT RFIC design. An ASK demodulator for the RFID tag was demonstrated using 3¿m LTPS TFT technology. The demodulator can operate at the carrier frequency of 13.56 MHz and the highest data rate is 100 kb/s.
