Claim Text:
1. A method for testing an Integrated Circuit (IC) with Near Field Communication (NFC) technology, the method comprising: generating a local oscillation signal to at least a transmitting path of the IC; generating the local oscillation signal to the receiving path for synchronizing the transmitting path and a receiving path of the IC; utilizing a BB modem of the IC to generate a known data pattern; modulating the known data pattern to generate a modulated data pattern, wherein the modulation is auxiliary carrier load modulation; sending the modulated data pattern on the transmitting path to an NFC antenna of the IC and utilizing the NFC antenna to loop the modulated data pattern back to the receiving path; demodulating the modulated data pattern; and determining if the data pattern on the transmitting path is the same as the data pattern on the receiving path; wherein it is determined that the IC fails when the data pattern on the transmitting path is not the same as the data pattern on the receiving path.
