The detection circuit includes: a first register unit, a triggering unit, a delay unit, a routing unit, and a second register unit, where the second register unit is connected to the triggering unit. A first signal is delayed in the delay unit, to obtain a second signal, a third signal is obtained according to the second signal, and logical operation is performed on the first signal and the third signal, to output a level signal to trigger an alarm unit. Because each unit may be implemented by using a digital circuit, a size of the circuit can be reduced."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and detection circuit for detecting security chip operating state","description":"The present invention provide a method and a detection circuit for detecting a security chip operating slate.
