Abstract: PURPOSE: A driving circuit and a driving waveform control method thereof are provided to reduce power consumption by determining amplitude and shape of a driving waveform by considering a waveform error difference. CONSTITUTION: A comparator(10) respectively compares the amplitude of a target waveform and the amplitude of a feedback waveform. The comparator revises a waveform error and an amplitude error. A waveform generator(20) revises the waveform and amplitude of an antenna driving waveform based on waveform error and amplitude error correction signals. An amplifier(30) amplifies and outputs the antenna driving waveform having the waveform and the amplitude. The comparator receives waveform and amplitude feedback of the antenna driving waveform from a transistor switch(40).
