ABSTRACT:
A data supply method for performing exact operations by a number of operation units receiving a single signal as input is proposed; and a composition of a system provided with both the filter function and the AD conversion function using the same is also proposed. The system comprises a charge signal supply unit, which is a charge splitter composed of charge transfer devices for splitting a input charge signal into N signal charge parts, for supplying as input for said charge splitter S (S is an integer equal or superior to 2) series of source time series charge signals as a single time series signal by multiplexing the same by the time division multiplexing; and a demultiplexing mechanism for taking as respective inputs the N outputs from said charge splitter, and for separating multiplexed S series of time series charge signals contained in this input to convert them into an independent time series signals.
