In this paper, we show a high dynamic range current-mode detector for computed tomography application. A regulated current mirror structure has been implemented at pixel level that provides with 17 bits dynamic range and a noise floor below 3 pARMS. Nonlinearity is kept below 2% and signal bandwidth is higher than 10 kHz. A test structure with 4times4 pixel array is presented is this paper. Both photodiode and current mode amplifier have been integrated into the same CMOS standard process
