Abstract:
An integrated circuit for near field communication (NFC) is provided. The integrated circuit includes a semiconductor substrate; a first transmitter disposed on the semiconductor substrate and configured to operate in a first NFC card mode, an NFC reader mode, and a peer-to-peer mode; a second transmitter disposed on the semiconductor substrate and configured to operate in a second NFC card mode; first transmitting pins connected to the semiconductor substrate and configured to transmit an output signal of the first transmitter to a first NFC antenna; second transmitting pins connected to the semiconductor substrate and configured to transmit an output signal of the second transmitter to a second NFC antenna; and a logic circuit disposed on the semiconductor substrate and configured to receive a control signal, and control an operation of the first transmitter and an operation of the second transmitter based on the control signal.
