Abstract
Provided are an RFID reader and a method for controlling a gain thereof. The RFID reader includes an amplifier and an AGC circuit. The amplifier controls the gain of an RX signal, received from an RFID tag, in response to an AGC signal. The AGC circuit measures a signal level in an ante-preamble period of the RX signal and generates an AGC signal to control the gain of the RX signal, on the basis of the measured signal level.
