The NFC device includes a protection system for protecting a transmit/receive system, and other systems, of the NFC device from potentially damaging voltages that may develop at an output of the antenna if the device enters a strong magnetic field. The protection system includes current control devices that are operative to source or sink current depending upon the polarity of a signal at an output of the antenna, to generate a voltage which at least partially negates a positive or negative voltage at the output of the antenna, thereby reducing the peak voltage at the antenna output."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Overvoltage protection for NFC devices","description":"The present application relates to a near field communication (NFC) device which has an antenna for receiving NFC signals.
