Abstract
Provided are a radio frequency identification (RFID) tag and a method for receiving a signal of the RFID tag. The RFID tag includes a voltage generator configured to generate a voltage signal from a received signal, a common gate circuit configured to convert the voltage signal into a current signal, a current/voltage converter configured to the current signal into a voltage signal by using a resistance value, a low-pass filter configured to perform low-pass filtering on the converted voltage signal, a buffer configured to buffer the low-pass-filtered voltage signal within an operation range, and a peak detector configured to detect a peak value from the buffered signal to demodulate information data. The current/voltage converter controls the resistance value to convert the current signal into a voltage signal included within the operation range of the buffer.
