METHOD FOR CONTROLLING AN ANTENNA NETWORK QUALITY FACTOR OF A NEAR FIELD COMMUNICATION DEVICE WITHOUT CHANGING MATCHING NETWORK, AND ASSOCIATED APPARATUS

摘要

A method for controlling an antenna network quality factor of an NFC device includes: determining whether a first data rate or a second data rate should be used for data communication during different time intervals, respectively; and when it is determined that the first data rate should be used during a first time interval of the time intervals, controlling a set of internal resistors positioned within a chip of the NFC device to have a first configuration during the first time interval, in order to adjust the antenna network quality factor. More particularly, the method further includes: when it is determined that the second data rate should be used during a second time interval of the time intervals, controlling the set of internal resistors to have a second configuration during the second time interval, in order to adjust the antenna network quality factor. An associated apparatus is also provided.

1. A method for controlling an antenna network quality factor of a near field communication (NFC) device, the method comprising:
determining whether a first data rate or a second data rate should be used for data communication during different time intervals, respectively, wherein the first data rate is different from the second data rate; and when it is determined that the first data rate should be used for data communication during a first time interval of the time intervals, controlling a set of internal resistors positioned within a chip of the NFC device to have a first configuration during the first time interval, in order to adjust the antenna network quality factor.
