Abstract
A transmitter of a NFC device includes a current detector which detects a first current flowing in an output node of a regulator and outputs a current detection signal related to a result of the detection, and a control block which compares the current detection signal with a reference current and generates a control signal for controlling a voltage of the output node according to a result of the comparison.
