Original Abstract Submitted
the present disclosure relates to power receiving devices and methods. an example power receiving device comprises an antenna cell array configured to receive a radio frequency (rf) signal from a transmission device, where the antenna cell array includes a first antenna cell and a second antenna cell, a first rectifier connected to the first antenna cell and having first maximum rectification efficiency when an input signal of the first rectifier has a first power value, a second rectifier connected to the second antenna cell and having second maximum rectification efficiency when an input signal of the second rectifier has a second power value different from the first power value, a first voltage converter configured to perform a first conversion of an output of the first rectifier, and a second voltage converter configured to perform a second conversion of an output of the second rectifier.
