Abstract: A driving method for a multiple frequency coupling generator is provided. The method includes: in normal operations, interpreting an input digital control signal transmitted from a digital signal processor into an interpreted digital control signal; interpreting the interpreted digital control signal into a plurality of magnetic coupling signals by a magnetic coupling switch circuit; performing signal recovery and differential delay on the magnetic coupling signals by an interlocking circuit for reducing time difference and signal loss of the magnetic coupling signals; and when the interlocking circuit determines that the magnetic coupling signals have substantially no time difference and no signal loss, transforming the magnetic coupling signals into a first driving signal and a second driving signal by a switch circuit, a driver circuit and an output pad group to drive a backend driving loop.
