TARIFA AMAYA, Ariel; DEL RISCO SANCHEZ, Arnaldo  and  CRUZ HURTADO, Juan Carlos. Modulator-Demodulator ASK with Manchester codification implemented with microcontroller PIC . EAC [online]. 2012, vol.33, n.3, pp. 63-69. ISSN 1815-5928.

This paper presents the design of a Digital Modulator-Demodulator ASK with Manchester codification implemented on microcontroller PIC 18F445 firmware, using the low frequency standard (LF) operating with frequency values between 125kHz. This modulator-demodulator is used in the implementation of an active RFID tag. It transmit when the device reader request the sensor temperature and the identifier. The device reader controls the communication with the tag. According to the specialized literature a similar system is not reported.

Keywords : ASK; RFID reader; RFID tag.
