What is disclosed is an apparatus for reducing row reset noise in photodiode based complementary metal oxide (CMOS) sensors. The apparatus uses at least one reference pixel for each row of pixels in a sensor array. Also, a reset noise elimination unit is provided to adjust the values received from the pixels in a particular row by an adjustment value determined from the reset values received from the reference pixels. Additionally, a method of using the apparatus is disclosed. The method has a step of providing a first reset signal to a row of pixels including the reference pixels. The method also reads out a first set of values from this row after integration. The method continues with providing a second reset signal to the row and a second set of values is read from the row. An adjustment value is calculated from the difference of the values which are read out from the reference pixels.

A compound die may be formed of two dies each having face and back sides, said dies being connected with said dies in face to face alignment. A radiation communication system may be used to assist in aligning the dies and in providing communications between the two dies. In this way, a composite structure may be produced which has advanced capabilities, a small footprint, and low impedance.
