Substrate electrical bounce compensation circuitry for digital cinematography image capture cameras

A charge coupled device (CCD) circuit comprising:

• a CCD array having a substrate;
• an electrometer coupled to an output of the CCD array having an output node;
• a video pedestal circuit comprising a reset drain bias supply and a reset field effect transistor (FET) having a source input coupled to the output of the CCD array, a source input coupled to the output node, and a drain;
• and
• a substrate bounce compensation circuit that capacitively couples an output of the CCD array to the drain of the reset FET, and resistively couples the drain of the reset FET to the reset drain bias capacitor to provide reset drain bias for the reset FET;
• which video pedestal circuit tracks and suppresses substrate bounce generated through a parallel drive signal that would normally cause output signal interference.
