Abstract: An imaging system includes a pixel that does not require a row select transistor. Instead, an operating voltage is selectively provided to the pixel's readout circuitry, and the readout circuitry provides output signals based on charge or voltage of a storage node. The operating voltage can be selectively provided to each row of a pixel array by a row driver. Each pixel includes a source follower transistor that provides an output signal on a column output line for readout. An anti-blooming transistor may be linked to each pixel's photosensor to provide an overflow path for electrons during charge integration, prior to transfer of charge to the pixel's storage node by a transfer transistor. Electrons not produced by an image are introduced to the photosensor prior to image acquisition, filling traps in the photosensor to reduce image degradation.

Abstract: A method for automatically measuring the modulation transfer function of an imager is disclosed. A opaque mask is placed over selected columns and rows of the imager during fabrication. In the course of an automated process, photons are uniformly shone over the image sensor. The amount of the input signal that flows from the unmasked pixel cells to the masked pixel cells can then be measured and the modulation transfer function can be determined.
