Abstract
A method for controlling a sensor to reduce reset noise is disclosed. The method including the steps of providing a reset command including a RESET signal and a first SAMPLE signal. The method also includes the steps of providing a read command including a first ADDRESS signal, a second SAMPLE signal, and a second ADDRESS signal. An apparatus including a system controller and a sensor controlled by the system controller is also disclosed. In one embodiment, the method and apparatus is provided for a sensor in a sensor array that is read-out in a pipelined fashion.
