ABSTRACT:
An array of active pixel sensor cells is operated to substantially reduce the gate induced drain leakage (GIDL) current component of the dark current. In addition, the array is tested to determine the number of cells in the array that are bad, and discards the array of active pixel sensor cells when the number of bad cells exceeds a predefined limit.
