Abstract

The use of mode locking phenomena in coupled oscillator arrays is exploited in order to generate multitone signals in an easy manner compared to existing multitone signal generation schemes. The generated multitone signals can be used in wireless power transmission towards improving the RF to DC conversion efficiency in rectifier circuits. Here a mode-locked signal is generated around 900 MHz using an array of two coupled oscillators. The performance of a rectifier circuit in terms of RF to DC conversion efficiency is evaluated using a one tone signal and using the generated mode-locked signal showing improved performance when using the mode-locked one.
