This paper is a progress report of the design and characterization of a monolithic CMOS detector with an on-chip ΣΔ ADC. A brief description of the design and operation is given. Backside processing steps to allow for backside illumination are summarized. Current characterization results are given for pre- and post-thinned detectors. Characterization results include measurements of: gain photodiode capacitance, dark current, linearity, well depth, relative quantum efficiency, and read noise. Lastly, a detector re-design is described; and initial measurements of its photodiode capacitance and read noise are presented. |
