    摘要: A hybrid detector or imager includes two substrates fabricated under incompatible processes. An array of detectors, such as charged-coupled devices, are formed on the first substrate using a CCD fabrication process, such as a buried channel or peristaltic process. One or more charge-converting amplifiers are formed on a second substrate using a CMOS fabrication process. The two substrates are then bonded together to form a hybrid detector.

    摘要: A symmetric pipelined charge-mode analog to digital converter including a signal-reference CCD channel having a plurality of charge storage stages that are arranged in a serial configuration to carry the signal and reference charges, and a CCD digital channel. A set of two step comparators coupled to the signal-reference channel first senses and stores the signal charge and then senses and compares the reference charge to the signal charge. In the first stage, an initial reference charge is used, and in subsequeant stages, an increment of one half the previous stage increment is added to the reference. In addition, at each stage, a charge increment equal to the previous reference increment is conditionally added to the signal charge and a corresponding bit in the digital channel is conditionally set responsive to the comparator. Thus, if the total signal charge is less than the total reference charge at a stage, the charge increment is added to the signal charge in the signal-reference channel, and a corresponding digital bit charge is zeroed in the digital channel. Conversely, if the total signal charge is larger than the told reference charge at a stage, the charge increment is not added to the signal charge and a corresponding digital bit charge is set to represent a one in the digital channel. One configuration provides a differential symmetric architecture wherein two signal-reference channels simultaneously feed a dual symmetric comparator providing enhanced symmetry thereby reducing threshold and offset sensitivity and susceptibility to environmental factors such as ionizing radiation.

    摘要: A six-phase charge coupled device (CCD) pixel includes a pixel pair, with each pixel having two adjacent control gates overlying corresponding variable potential wells, where voltages applied to the control gates enable charge to be accumulated into and transferred out of the wells. A clear window region overlies a fixed potential gradient region, decreasing in potential away from the control gates. This region enables a wide band of photons to be sensed by the photosensitive silicon of the CCD. The decreasing potential levels facilitate high charge transfer efficiency (i.e., high CTE) from pixel to pixel via the control or transfer gates. By applying particular voltages to the control gates, charge can be quickly and efficiently transferred between pixels. In addition, the window provides a self aligned mask for the implantation steps and thus prevents the formation of pockets (or wells) due to misalignments that decrease the charge transfer efficiency and causes non-uniformity problems as associated with prior art. Furthermore the window provides a flat region that can be covered with an anti-reflective (AR) coating layer, thus further increasing the quantum efficiency.

    摘要: A charge coupled device (CCD) includes a low noise charge gain circuit that amplifies charge of a cell dependent upon the charge accumulated by the cell. The low noise charge gain circuit receives clocking signals, such as from an input diode, which allow charge to accumulate in a reservoir well and then flow into a receiving well. The low noise charge gain circuit also receives a voltage signal corresponding to charge accumulated on an associated cell. The amount of charge flowing into the receiving well depends on this voltage signal.

    摘要: A plurality of unit pixels in a two dimensional imaging array are arranged in a manner that signal charges along a given row are added to other relevant signal charges of the same row. Signal charges along a given column are added to other relevant signal charges of the same column. Summed charge values are output simultaneously from rows and columns to produce one row and one column of image data. The resulting summed data is temporarily stored in on-chip buffers and then output from the chip during the integration time of the next imaging cycle with no loss in imaging duty cycle.
