摘要:
A contactless device including a transmission antenna configured to transmit a transmission signal; a pickup antenna configured to detect a field generated by a pickup signal, which comprises a response signal transmitted from another contactless device and the transmission signal; and a cancellation circuit configured to subtract a voltage of the transmission antenna from a voltage of the pickup antenna.
