For example, a signal power management circuit comprises a rectifier that is configured to rectify a received radio frequency signal and output a first rectified voltage, a first regulator that is configured to maintain the first rectified voltage at a predetermined first voltage level, and a second regulator that is configured to receive an output of the first regulator and maintain a second rectified voltage different from the first rectified voltage at a predetermined second voltage level. A signal detector of the signal power management circuit is configured to receive the first rectified voltage and the second rectified voltage and detect a signal component of the received radio frequency signal on the basis of a difference between the first voltage level of the first rectified voltage and the second voltage level of the second rectified voltage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Signal power management circuits and smart cards including the same","description":"Signal power management circuits and smart cards including the same are provided.
