    摘要: A wirelessly powered medical implant system comprising: a power source system including: an automatic gain controller to receive input power, automatically adjust the input power based on a feedback signal with an offset phase delay, and provide the adjusted input power as output power; a source resonator to generate, based on the output power, a magnetic field to transmit wireless power via the magnetic field, and provide the feedback signal; and an offset phase delay circuit to receive the feedback signal from the source resonator, generate the offset phase delay, and include the offset phase delay with the feedback signal; and a medical implant including: an implant resonator to receive the transmitted wireless power via the magnetic field; and one or more sensors, wherein the feedback signal is based on inductive coupling of the magnetic field between the source resonator and the implant resonator.
