In one embodiment, the circuit comprises a rectifier circuit configured to be coupled to an NFC antenna for receiving an antenna voltage, a filter coupled to an output of the rectifier circuit and configured to provide the rectified and smoothed antenna voltage as supply voltage, and a current limiting device coupled between the filter and an output node and configured to limit an output current provided at the output node dependent on a control signal. Further, the power supply circuit comprises a control circuit configured to receive the supply voltage and a reference voltage and to generate the control signal dependent on a difference between the reference voltage and the supply voltage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power supply circuit that sources energy from an NFC antenna","description":"A power supply circuit is described herein which is capable of sourcing energy from an NFC antenna.
