Abstract: Described are a NFC apparatus, an electronic device and a signal processing method. The NFC apparatus includes a NFC controller, a NFC antenna, and a balanced to unbalanced converter. The balanced-to-unbalanced converter comprises a primary coil and a secondary coil. The primary coil is connected to the NFC controller. Coupled to the primary coil, the secondary coil is connected to the NFC antenna. The balanced-to-unbalanced converter is configured to convert a first current signal in the form of a pair of differential signals generated by the NFC controller to a second current signal in the form of a single-ended signal received by the NFC antenna, and amplify a magnitude of the first current signal to a magnitude of the second current signal through a coupling relationship with a ratio between a first impedance of the primary coil and a second impedance of the secondary coil as N: 1.
