The fingerprint detecting circuit includes a conductive layer to couple a touch from the finger; and an amplifier including a first input terminal coupled to the conductive layer; a second input terminal to receive a second signal; and an output terminal, wherein a first capacitance is between the output terminal and the first input terminal; wherein a phase of the first signal is inverse to a phase of the second signal. The present invention utilizes the two signals with the inverse phases to drive the fingerprint detecting circuit, so as to enhance strength of the output signal and lower hardness of fingerprint detecting. Power consumption and production cost are reduced, and the requirement of conventional voltage for the portable electronic device is satisfied."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fingerprint detection circuit and fingerprint recognition system","description":"The present invention provides a fingerprint detecting circuit applied in a fingerprint identification system, wherein the fingerprint identification system transmits a first signal to finger.
