In this paper a new fully integrated detector architecture for pick-up units in optical storage systems is presented. Apart from a special diode constellation for data recovery it features a 5/spl times/5 diode matrix for determination of the average spatial light power distribution across the detector. The chip, fabricated in a standard 0.6 /spl mu/m CMOS process, operates at a 3.3 V power supply and occupies 1.78/spl times/1.58 mm/sup 2/. It includes six high frequency readout and one low frequency readout paths.
