PHOTODIODE ARRAY OUTPUT SIGNAL MULTIPLEXING

摘要

There is disclosed an imaging system comprising: a first integrated circuit including a photodiode array comprising a plurality of integrating photodiode elements formed in an array of rows and columns, the integrated circuit providing a plurality of output signals corresponding to an output of each photodiode; and a second integrated circuit for receiving as inputs the plurality of output signals from the first integrated circuit and including a plurality of multiplexers corresponding to the number of columns in the array, the outputs signals from a respective column forming inputs to a respective multiplexer, each multiplexer for selectively connecting one of the output signals to a multiplexer output, wherein each multiplexer is selectively switched between the plurality of output signals by a plurality of control lines, the number of control lines corresponding to the number of rows in the array.
