ABSTRACT:
Provided is a demodulator circuit allowing a tag or transponder to efficiently recover data of an input amplitude signal at very low power in a wireless communication system such as a radio frequency identification (RFID) system. The demodulator connects an output of a voltage multiplier to a low-current path by capacitive coupling, thereby recovering data. Therefore, data is recovered, at low power, from an input amplitude signal having a low modulation depth, and it is possible to increase a communication distance.
