Patent 8222965 was granted and assigned to Dust Networks on July, 2012 by the United States Patent and Trademark Office.
A modulator for modulating a radio frequency signal comprises a voltage controlled oscillator, a first feedback path, and a second feedback path. The first feedback path is coupled between a detector output and the voltage controlled oscillator. The second feedback path is coupled between the detector output and the voltage controlled oscillator. The detector is coupled to a divided down output of the voltage controlled oscillator and a reference clock.
