Abstract: A linear array of 64 BDJ cells has been designed and fabricated in a 1.2 $mu@m CMOS process. It is aimed to build anew, self-calibrated micro-spectrophotometer. Each cell contains a BDJ detector which can operate as booth light intensity-sensitive and wavelength-sensitive device, and makes use of MOS transistors working in the weak inversion mode to perform logarithmic current-voltage conversion. Measurement of the fabricated chip has been carried out. A large detection light intensity dynamic range and a low fixed pattern noise have been obtained. !10
