Abstract:
An image sensor may include an array of pixels arranged in rows and columns. The array of pixels may operate in a global shutter mode. Each pixel in the array of pixels may have a floating diffusion node for storing charge and may include an active reset circuit that acts as an inverting amplifier and that resets the floating diffusion node to a predetermined reference voltage, which eliminates the need for correlated double sampling readout. A sampling circuit may be coupled to the active reset circuit. The sampling circuit may sample and store signals that correspond to the amount of charge stored at the floating diffusion node. The sampling circuit may pass stored signals to a column sensing line through an amplifier. The amplifier may include a source follower transistor that provides proportional amplification to the stored signals and may include an active reset circuit for resetting the sampling circuit.

Claim (Index 1):
An image sensor pixel comprising:\n a photosensitive element that generates charge in response to incident light; a floating diffusion node coupled to the photosensitive element; a first transistor having a gate coupled to a reference voltage; a second transistor having a gate coupled to the floating diffusion node, a source terminal coupled to a voltage supply, and a drain terminal coupled to a ground through the first transistor; and a third transistor coupled between the floating diffusion node and the drain terminal of the second transistor; and a sampling circuit coupled to the source terminal of the second transistor.
