  • Substrate electrical bounce compensation circuitry for digital cinematography image capture cameras
    Patent number: 7064786
    Abstract: A charge coupled device (CCD) circuit employing substrate electrical bounce compensation circuitry that is particularly useful in a cinematography digital image capture cameras. An exemplary CCD circuit comprises a CCD array having a substrate that is coupled to an output node. The output of the CCD array (substrate) is coupled to a gate input of a reset field effect transistor (FET). The output node is coupled to a source input of the reset FET. The output of the CCD array is coupled to the substrate bounce compensation circuit which provides a video pedestal reference signal for the reset FET. The substrate bounce compensation circuit includes a capacitor that capacitively coupled the output of the CCD array to the drain of the reset FET, and a resistor that resistively couples the drain of the reset FET to a reset drain bias capacitor.
