近距離通信デバイスシグナリングにおいて位相ノイズを減らすための装置および方法 |
摘要 |
A method for communication between near field communication (NFC) devices includes generating a transmission signal, an in-phase local oscillator signal, and a quadrature local oscillator signal from edges of an input clock signal. The method further includes mixing a load modulated signal with the in-phase local oscillator signal to generate an in-phase baseband signal. The method further includes mixing the load modulated signal with the quadrature local oscillator signal to generate a quadrature baseband signal. The method further includes adjusting a phase delay of at least one of the in-phase local oscillator signal or the quadrature local oscillator signal in response to a first signal strength of the in-phase baseband signal and a second signal strength of the quadrature baseband signal. |
