A regulated current mirror structure has been implemented at pixel level that provides with 17 bits dynamic range and a noise floor below 3 pA[RMS]. Non-linearity is kept below 2% and signal bandwidth is higher than 10 kHz. A test structure with 4x4 pixel array is presented in this paper. Both photodiode and current mode amplifier have been integrated into the same CMOS standard process.enimage sensorcomputed tomographyhigh dynamic rangecurrent mode detectorDetektorComputer-TomographieCMOSPhotodiode621conference paper
