WIRELESS POWER FOR SENSOR ARRAYS

Abstract:

A wireless power system includes a phase locked loop (PLL) providing an input signal tuned in frequency, a plurality of dividers coupled to the PLL to divide the frequency of the input signal, a plurality of phase interpolators electrically connected to the plurality of dividers to generate multiple phases based on the input signal, and a plurality of drivers electrically connected to the plurality of phase interpolators to direct a plurality of output signals each having a different frequency to a plurality of sensor clusters, each sensor cluster operating at a different frequency.
