Abstract
An NFC transmitter using a delay-locked loop and an NFC transmission method thereof are provided. The NFC near field communication (NFC) transmitter includes a delay-locked loop (DLL) that outputs a reference clock and a delayed clock using the reference clock and a value of a duty code which are input, a clock output unit that receives the reference clock and the delayed clock, outputs the reference clock in any of a high section and a low section of input data, and outputs a converted clock having a duty ratio using the reference clock and the delayed clock in the other of the high section and the lower section of the input data, and an RF signal generator that generates an RF signal using a PWM (Pulse Width Modulation) signal input from the clock output unit.
