ABSTRACT:
A device for cyclically sampling the output voltage of a column of electrodes in a two-dimensional array of radiation detectors. The device samples the column voltage three times within a cycle and combines these samples in a manner which cancels out any linear change in column voltage with time during the cycle and obtains a measure of the voltage change due to charge transfer from a selected electrode in the column to an adjacent row electrode.
