A near field communication (NFC) device operating in a tag emulator mode, including a controller to output a control signal to control operation of a transistor, a waveform shaper to shape the control signal and to generate a shaped signal by increasing a rise time and a fall time of the control signal, and the transistor to receive the shaped signal and to output a switching waveform to drive an antenna of the NFC device.
