Abstract

See full text

A two dimensional array of digital imaging pixels each include a photo-sensing element and a readout element. A test element within the two-dimensional array, a column of test elements peripheral to the array, or test monitoring circuits peripheral to the array are constructed using the same process as the readout elements. The test element within the array and the column of test elements are connected to a first and second external voltage sources. The test element within the two-dimensional array and the column of test elements may be connected to a test data line or to a data line used by the imaging pixels.
