Title:
NFC TAG INTERFACE FOR ENERGY ACQUISITION AND SMALL-SIZE OPTIMIZATION
Document Type and Number:
WIPO Patent Application WO/2017/166365
Kind Code:
A1
Abstract:
The present invention falls within the technical field of wireless communications, and particularly relates to an NFC tag interface for energy acquisition and small-size optimization. The NFC tag interface comprises an antenna, an adjustable matching circuit, a demodulator, a load modulation circuit, a data interface, a rectification voltage stabilizing circuit and an energy acquisition interface, wherein the antenna, the adjustable matching circuit, the demodulator, the load modulation circuit and the data interface constitute an NFC data receiving loop; and the antenna, the adjustable matching circuit, the rectification voltage stabilizing circuit and the energy acquisition interface constitute an NFC energy receiving circuit. The beneficial effects of the present invention are that: the present invention allows an NFC communication interface to use a small-size antenna without affecting the NFC communication performance. The small-size antenna makes device development become very flexible, thereby greatly lowering the development difficulty of an NFC system. The present invention greatly expands the application range of an NFC communication interface currently and in the next few years.
