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.
