In MediaTek’s vision of an inclusive future, users around the globe have access to mobile technologies, from smartphones to tablets, premium to mainstream. MediaTek now offers power on the go—technologies that bring ease of use, low cost and high reliability and flexibility to wireless charging, bridging the gap between tightly coupled solutions and loosely coupled solutions. MediaTek’s innovative approach to highly-integrated multi-mode wireless power receivers allows smartphones, tablets and other devices to charge on loosely or tightly coupled systems. This white paper provides background on the physics behind inductive and resonant technologies.
