Response mode detection of a linear-logarithmic image sensor using a current–mode readout circuit
A current-mode image sensor architecture using a linear-logarithmic pixel in order to improve the dynamic range is presented. The pixel cell is based on a 3T active pixel structure with a PMOS readout transistor in the linear region of operation and a PMOS reset transistor that allows for a linear-logarithmic response. An intrascene dynamic range of 90dB is obtained with a pixel fill factor of ...
متن کاملA Cmos Current-mode Multiplier/divider Circuit
Combination of A/D-D/A converters allows implementing multiplier/divider operations. An efficient design based on continuous-time, current-mode, dividing-algorithmic converters is presented in this paper. It offers high speed and capability of low voltage operation, and it is suitable for applications of low or middle resolution (below 9 bits). In addition, the division result is given in both ...
