摘要： An integrated circuit includes first and second coils, a first pad connected to the first coil and to a resonator, a second pad connected to the second coil and to the resonator, and first and second output terminals. The first pad is arranged to provide signals between the resonator and the first coil. The second pad is arranged to provide signals between the resonator and the second coil. A distance between the first pad and the first coil is less than a distance between the first coil and the first output terminal and a distance between the first coil and the second output terminal. A distance between the second pad and the second coil is less than a distance between the second coil and the first output terminal and a distance between the second coil and the second output terminal.
