ABSTRACT:
In interline transfer type image sensing devices, photogenerated charge is transferred from a collection node into a charge coupled shift register. The framing rate of these detectors is typically limited by the maximum readout rate of the shift register. A CCD image sensing device with multiple shift register outputs for higher framing rate, utilizes alternating shift register orientations and multiplexing of multiple shift registers to a each output in order to match the pitches of the detector columns and output bondpads. This configuration allows detectors of different size to be made more easily. This detector additionally uses a combination of low-lag photodiodes, low transfer inefficiency true two-phase charge coupled shift registers, and low noise charge sensing amplifiers to provide non-interlaced readout of the image with minimum signal loss and noise while operating at high frame rates.
