摘要：
An exemplary system for communicating with or providing power to an implantable stimulator includes a coil configured to emit a magnetic field for driving a corresponding circuit in the implantable stimulator and a coil driver circuit configured to drive the coil with a tuning frequency. The coil driver circuit actively adjusts the tuning frequency such that the coil operates at a frequency substantially equal to a resonant frequency. An exemplary method of communicating with or providing power to an implantable stimulator includes driving a coil with a tuning frequency and actively adjusting the tuning frequency such that the coil operates at a frequency substantially equal to a resonant frequency. The coil emits a magnetic field used to drive a corresponding circuit in the implantable stimulator.
