When a voltage of the antenna terminal is higher than the sum of this band-gap reference voltage value and the respective threshold voltage of the serial MOS transistors, the threshold unit is turned ON to switch on a grounded path, so that charge at the antenna is output to the ground; in this way, the amount of charge at the antenna terminal is reduced and the rectified DC voltage is thus reduced. When the voltage at the antenna terminal is lower than the sum of this band-gap reference voltage value and the respective threshold voltage of the serial MOS transistors, the threshold unit is turned off to switch off the grounded path. The rectifier circuit rectifies all the charges at the antenna end into DC power for powering the load circuit. In this way, the function of continuously adjust the limited voltage is achieved, so that the limited voltage value has continuity and accuracy, and the stability of the operating voltage value of the circuits is guaranteed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Limiter circuit capable of continuously adjusting amplitude of rectified signal and passive radio frequency tag","description":"In the present invention, by connecting a band-gap reference voltage module unit to a threshold unit of a limiter circuit, the ON-voltage of the threshold unit can be dynamically and continuously cont","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9792540","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
