Abstract: A chip device with a number of individually powered parts, such as photoreceptors. A mesh is provided to provide power to the individual photoreceptors. The mesh may be provided for ground and power and/or both. The mesh may be on different layers, so that one portion of the mesh is exactly over the other portion of the mesh. The mesh takes up a portion of real estate on the chip in between the individual photoreceptors, in locations where image sensing parts cannot be located. In an embodiment, the mesh can be intentionally broken at various locations to optimize the path length.

Abstract: A method and associated architecture for dividing column readout circuitry in an active pixel sensor in a manner which reduces the parasitic capacitance on the readout line. In a preferred implementation, column readout circuits are grouped and provided with group signaling. Accordingly, only column output circuits in a selected group significantly impart a parasitic capacitance effect on shared column readout lines. Group signaling allows increasing pixel readout rate while maintaining a constant frame rate for utility in large format high-speed imaging applications.

Abstract: A dual slope A/D converter uses two opposite sense ramps added to its differential input. The value in a digital counter is latched at the time when the two ramps intersect. This enables a more consistent switching point, allowing the amplifier to the linear over a larger part of its range.

Abstract: A CMOS active pixel color linear image sensor is operable in line-packed readout mode, and at very high speed. In accordance with a preferred embodiment, the sensor is formed entirely on a single-chip and may be further configurable for operation in parallel-packed and/or pixel-packed modes. Line-packed pixel readout is accomplished by spreading same color pixel signal sampled values in storage elements across each of plural readout register arrays in a “cyclic” manner. Facility is introduced for starting the reading of a next pixel (e.g., R pixel 2) even before the previous pixel (R pixel 1) has been read out to increase the effective pixel readout rate.
