本发明涉及具有可调节增益的近场通信设备，具体公开了一种能优化对接收信号的增益的近场通信设备。对从近场通信环境接收到的信号进行测量，并将其与一个或多个临界值保持值相比较。根据比较，确定测量值指示放大不足还是放大过度。根据分析结果，分别调节近场通信设备内的一个或多个组件以增大或减小增益。该测量可在空载基准状态期间或在加载期间进行，且可与先前测量值相比较以评估其准确性。

A near field communications (NFC) device is disclosed that is capable of optimizing a gain for received signals. Measurements are made of signals received from an NFC environment and are compared to one or more threshold hold values. Based on the comparison, it is determined whether the measurements indicate underamplification or overamplification. Depending on the results of the analysis, one or more components within the NFC device is adjusted to increase or decrease the gain, respectively. The measurements may be taken during an unloaded baseline state or during loading, and may be compared to previous measurements to estimate their accuracy.
