Abstract
This paper presents a reconfigurable cross-
connected (CC) wireless power transceiver (TRX) operating
at 6.78 MHz and implemented for bidirectional device-to-device
(D2D) charging with high efficiency and small system volume.
We propose, for the first time, a CC topology applied to a
differential class-D power amplifier for significant switching
loss reduction. Two delay-locked loops (DLLs) for each power
NMOS transistor form the reconfigurable controller, realizing
the adaptive deadtime control in th
