Patent ID: 11942796
Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATION
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. A method comprising:
generating an input signal tuned in frequency by a phase locked loop (PLL);
dividing the frequency of the input signal by a plurality of dividers coupled to the PLL, wherein the plurality of dividers provides a plurality of phases for the input signal;
electrically connecting a plurality of phase interpolators to the plurality of dividers to generate multiple phases based on the input signal, each divider associated with a group of phase interpolators; and
electrically connecting a plurality of drivers to the plurality of phase interpolators, the plurality of phase interpolators selecting phases from the plurality of phases for the input signal to digitally direct a plurality of output signals each having a different frequency from the plurality of drivers to a plurality of sensor clusters, wherein electromagnetic coupling is used for near field sensor clusters and radiating elements are used for far field sensor clusters.
