The front-end circuit includes a transistor having a threshold voltage that affects a relationship between the output signal and the level of the detection quantity. This transistor has a biasing node via which a biasing voltage can be applied to a semiconductor region that affects the threshold voltage of the transistor. A replica of the front-end circuit receives at least one defined input signal, among which is a substitute of the detection quantity having a defined level. The replica is arranged in a control loop that controls the biasing voltage that is applied to the biasing node in the replica, so that the replica provides a defined output signal. This biasing voltage is then also applied to the biasing node in the front-end circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image sensor","description":"In an image sensor, a front-end circuit provides an output signal indicative of the amount of light in response to at least one input signal.
