Image Sensor Having Column-level Correlated-double-sampling Charge Transfer Amplifier
1 Jul 21
Correlated double sampling column-level readout of an image sensor pixel may be provided by a charge transfer amplifier that is configured and operated to itself provide for both correlated-double-sampling and amplification of floating diffusion potentials read out from the pixel onto a column bus after reset of the floating diffusion (I) but before transferring photocharge to the floating diffusion (the reset potential) and (ii) after transferring photocharge to the floating diffusion (the transfer potential).

Utility
Column-interleaved Pixel Array
20 May 21
Shared-readout pixels conventionally disposed in two or more physical columns of a pixel array are spatially interleaved (merged) within a single physical column to yield a pixel array in which each physical pixel column includes two or more logical columns of shared-readout pixels coupled to respective logical-column output lines.

Utility
Scalable-pixel-size Image Sensor
20 May 21
Photodetection elements within an integrated-circuit pixel array are dynamically configurable to any of at least three uniform-aspect-ratio, size-scaled pixel footprints through read-out-time control of in-pixel transfer gates associated with respective photodetection elements and binning transistors coupled between the transfer gates for respective clusters of the photodetection elements and a shared reset node.

Utility
Variable-Width Source-Follower Transistor for Reduced Noise in CMOS Image Sensors
11 Nov 20
An image sensor (e.g., an image sensor pixel) includes floating diffusion to receive charge, an output node to provide a voltage corresponding to the charge in the floating diffusion, a current supply, and a MOSFET in a source-follower configuration: the MOSFET includes a source coupled to the current supply and to the output node and a drain coupled to a voltage supply.
