Embodiment 1
[0045] The SOC communication chip combining NFC, power carrier and wireless of the present invention is a communication chip integrating NFC, PLC and WiFi. A single SoC chip includes NFC front end (AFE) / physical layer (PHY), PLC analog front end (AFE) , PLC physical layer (PHY), PLC data link layer (MAC); WiFi analog front end (AFE), WiFi physical layer (PHY), WiFi data link layer (MAC); also includes MCU microprocessor and its corresponding chip interface;
[0046] In order to save the area of NFC, PLC and WiFi integrated chips, the modules of PLC and WiFi are shared to the greatest extent. Such as figure 1 As shown, the PLC input signal passes through the baseband low noise amplifier (101), and the signal after the WiFi input signal passes through the RF low noise amplifier and the mixer (102) is sent to the same receiving circuit, including the baseband signal amplifier (103), Low-pass filter (104), analog-to-digital converter (105), and digital filtering of the digital...
