Abstract
Provided are a Radio Frequency IDentification (RFID) tag with a signal reception method. The RFID tag includes a demodulator that receives a read signal containing read data. The demodulator includes; a voltage generating circuit that provides a first voltage signal and a second voltage signal derived from the received read signal, an inverter that provides a data pulse signal indicative of the read data by inverting the second voltage signal using an inverting voltage defined in relation to the first voltage signal, and a buffer that recovers the read data by buffering the data pulse signal.
