Abstract
A video buffer of a focal plane array (FPA) electrical interface module is presented for providing output capacitance cancellation. The buffer has a capacitance cancellation stage (50) for receiving an analog signal produced by a FPA. The cancellation stage (50) includes an amplifier having a gain greater than unity for amplifying the analog signal and positive feedback capacitor for reducing power requirements and providing an increased pixel rate for the system. A dc restoration stage (52) is included for setting the analog signal to a dc level that is required by an external system and a line driving stage (54) for driving a video cable from the buffer to the external components of the system.
