Each pixel may have a photodiode that receives light through the back surface, a floating diffusion node, a charge transfer gate, and first and second reset transistor gates. A source follower transistor may have a gate coupled to the floating diffusion node and a source coupled to an addressing transistor. The pixel may be coupled to a column feedback amplifier through the addressing transistor and a column feedback reset path. The amplifier may provide a kTC-reset noise compensation voltage to the reset transistors for storage on a holding capacitor coupled between the floating diffusion and a drain terminal of the source follower. The floating diffusion may be bounded at the front surface by the transfer gate, the reset gate, and p-type doped regions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Global shutter image sensor pixels having improved shutter efficiency","description":"An image sensor may be provided with an array of image sensor pixels formed on a substrate having front and back surfaces.
