摘要： A focal plane array detector method and system and the detector circuit comprising a plurality of detector circuits, each of the detector circuits comprising a first capacitor having upstream and downstream electrodes, circuitry for periodically applying a predetermined constant voltage source to the downstream electrode and then removing the constant voltage source from the downstream electrode, a photodetector for applying an input signal to the upstream electrode, a signal storage device for storing the input signal on the downstream electrode at the first capacitor and a coupling device for periodically coupling the signal storage device to and uncoupling the signal storage device from the downstream electrode a predetermined time after the constant voltage source has been removed from the upstream electrode and a multiplex circuit coupled to each of the signal storage devices for providing a serial output of the signals stored on the signal storage devices. The system is disposed on a single semiconductor chip.
