An auto-zero switch is coupled between an input of the common source amplifier and an output of the common source amplifier. A feedback capacitor is coupled to the input of the common source amplifier. An offset switch is coupled to the feedback capacitor and is further coupled to a reset voltage and an output of the amplifier circuit. The auto-zero switch and the offset switch are configured to couple the feedback capacitor to the reset voltage during a reset of the amplifier circuit. The offset switch is configured to couple the feedback capacitor to the output of the amplifier circuit after the reset of the amplifier circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Column amplifier reset circuit","description":"An amplifier circuit for use in an image sensor includes a common source amplifier coupled to receive an input signal representative of an image charge from a pixel cell of the image sensor.
