摘要: A method of implementing dynamic ground sharing in an image sensor with pipeline architecture starts with a pixel array capturing image data. Pixel array includes pixels to generate pixel data signals, respectively. A readout circuitry acquires the image data from a row in the pixel array. An analog-to-digital conversion (ADC) circuitry included in the readout circuitry samples the image data from the row to obtain sampled input data. When the ADC circuitry is sampling, a ground sharing switch is closed to couple the pixel array and the ADC circuitry to a common ground. When the ADC circuitry is not sampling, the ground sharing switch is open to separate the pixel array and the ADC circuitry from the common ground. The ADC circuitry converts the sampled image data from analog to digital to obtain an ADC output. Other embodiments are described.

摘要: High speed rolling image sensor includes pixel array disposed in first semiconductor die, readout circuits disposed in second semiconductor die and conductors. Pixel array is partitioned into pixel sub-arrays (PSAs). Each of the PSAs includes a plurality of pixels. Pixel groups include pixels that are non-contiguous, non-overlapping and distinct. Each pixel group includes pixels from different PSAs. Each pixel group is coupled to a corresponding analog-to-digital converter and memory unit tiles (ADMs) respectively included in readout circuits. ADMs respectively include (i) analog-to-digital (ADC) circuits that convert the image data from pixel groups from analog to digital to obtain ADC outputs, and (ii) memory units to store ADC outputs. Conductors are coupling pixel array to ADMs. Conductors include number of conductors per column of pixel array. Number of conductors per column of pixel array may be equal to number of pixels in PSA arranged in same column. Other embodiments are described.

摘要: Because a conventionally known imaging apparatus includes a buffer element for each signal processing circuit, the number of buffer elements increases in proportion to the number of signal processing circuits. The delayed supply of a drive signal within a group of a plurality of signal processing circuits may require the operation timing margin to be set longer. In other words, the operational speed is hard to increase. First buffer circuits connected in series and second buffer circuits connected in parallel with the first buffer circuits are provided, and one second buffer circuit supplies a drive signal to a plurality of signal processing units.
