IMAGE SENSOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240179435 titled 'IMAGE SENSOR

Simplified Explanation

The image sensor described in the abstract includes a pixel array with multiple pixels, each containing a photodiode, a floating diffusion node, capacitors, and sampling transistors to capture and store photocharge generated by the photodiode.

  • Photodiode in each pixel captures light and generates photocharge.
  • Floating diffusion node integrates the photocharge.
  • First capacitor stores charge corresponding to the voltage of the floating diffusion node.
  • First sampling transistor samples charge to the first capacitor.
  • Second capacitor stores charge corresponding to the integrated photocharge.
  • Second sampling transistor samples charge to the second capacitor.
