  • Image sensor having normalized areal conductive elements to effect uniform capacitative loading
    Patent number: 4660089
    Abstract: In an area image sensor, the on-chip capacitances driven by the sensor photosite elements during sensor readout are made equal. This is accomplished by adjusting the lengths and widths of the conductors (and leads) carrying the output signals so that each signal conductor (and lead) covers equal areas on the sensor substrate. Additionally, the invention teaches fabricating individual integrated circuit buffer amplifiers on the sensor chip which isolate the normalized capacitances from loading effects due to externally connected circuits.
