The fingerprint sensor comprises sensing elements configured to generate a sensing signal in responsive to a finger-touch action. The circuit for signal processing comprises: a biasing circuit for generating a biasing signal; an amplifier for generating an analog output signal according to the sensing signal; and an analog-to-digital converter for converting the analog output signal into a digital output signal. In the noise detection mode, the amplifier is configured to amplify a superposed signal of the sensing signal and the biasing signal to generate a first analog output signal, and the operating frequency of the amplifier is adjusted according to the first analog output signal. In the image acquisition mode, the amplifier is configured to amplify the sensing signal for generating a second analog output signal, and generate a fingerprint image according to the second analog output signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Circuit and method for signal processing in fingerprint sensor","description":"Disclosed is a circuit and a method for signal processing in a fingerprint sensor.
