    Abstract: A circuit for an image sensor pixel receives photogenerated information from an image sensor, such as infrared sensor. The circuit includes a single ended operational amplifier, they can have a simple circuit such as for example 4 transistors. An additional transistor is used in the pixel to regulate the voltage that is used to drive the operational amplifier, to maintain that voltage relative to a bias level. This prevents voltage fluctuations, which would otherwise be passed to the pixel output.

    Abstract: An image sensor array that has a buffer amplifier, having a capacitor which receives photogenerated energy from a photodetector, and stores the photo generated energy in a capacitor of the buffer amplifier. A reset across the buffer amplifier is applied at a time which is sufficient to allow the amplifier to settle transiently prior to applying the clamp voltage. There is also a source follower that is enabled to operate at a time just before snapshot operation, and then turned off when the snapshot is over, to save on power.
