  • Publication number: 20070012965
    Abstract: One photodetection system includes a wide bandgap photodetector array which is physically and electrically integrated on a flexible interconnect layer including electrical connections, which is packaged in a manner for being electrically integrated with processing electronics such that the packaging and the processing electronics are configured for obtaining and processing signals detected by the photodetector array, or which includes both the flexible interconnect layer and processing electronics packaging features. Another photodetection system includes a wide bandgap focal plane array module including a photodetector pixel array, scan registers, a substrate supporting the array and the scan registers, and electrical interconnections coupling each pixel to at least two of the scan registers.

  • Publication number: 20060139198
    Abstract: A system and a method for converting an analog signal to a digital signal are provided. The technique involves receiving a sampled analog signal, and selecting one of a plurality of segments of a segmented relation between DAC output values and desired ADC input values. Desired gain and offset values are applied to the DAC output values or to the sampled analog signal based upon the selected segment. The sampled analog signal is converted to a digital signal based upon the desired gain and offset values.

  • Publication number: 20060038712
    Abstract: A multi-channel analog to digital conversion circuit and methods thereon are provided. The multi-channel analog to digital conversion cirucit comprises a plurality of linearized channels wherein each channel comprises a multi-stage pipelined charge-to-digital converter and an integrating capacitor within each stage of the multi-stage converter wherein analog residue is processed by subsequent analog to digital converter stages. Each stage of respective linearized channels is configured for calculating gain and offset for each stage in the channel and such gain and offset is used in subsequent integration periods.

  • Publication number: 20050286682
    Abstract: A detector module for use in an imaging system is provided. The detector comprises at least one sensor array configured for receiving X-ray signals and converting the X-ray signals to corresponding electrical signals, at least one electronic device configured for converting the electrical signals to a corresponding digital signal and a switching circuit coupling the sensor array and the electronic device, wherein the switching circuit is configured for routing the electrical signals from the sensor array to the electronic device.
