The first rectifier receives an antenna voltage through a first power terminal and a second power terminal, rectifies the antenna voltage and provides a first rectified signal to a first node. The shifting rectifier is enabled in response to an enable signal, receives the antenna voltage through the first power terminal and the second power terminal, increases a direct current (DC) level of the antenna voltage, rectifies the increased DC-level antenna voltage and provides a shifted rectified signal to the first node. The field monitor receives the antenna voltage through the first power terminal and the second power terminal, monitors a magnitude of the antenna voltage and generates the enable signal which is activated when the magnitude is smaller than a reference value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Demodulator for near field communication, near field communication device, and electronic device having the same","description":"A demodulator for a near field communication (NFC) includes a first rectifier, a shifting rectifier, a field monitor and an edge detector.
