Abstract

A resonate power generator is provided. The resonate power generator may include a waveform and sequence memory to record a predetermined waveform and a predetermined sequence, a delta-sigma modulator to delta-sigma modulate an output signal of the waveform and sequence memory, and a waveform recovery unit to receive, as an input, an output radio frequency (RF) signal of the delta-sigma modulator, and to convert the input into a waveform in a form of an impulse.
