Abstract

PURPOSE:To obtain a large amount of the output signal with reduced number of FET by dividing the plus and minus split electrodes into N-groups each and then drawing out the output signal from each group via FET provided at the signal output part of each group. CONSTITUTION:The CCD filter is realized through an addition between the output voltage given from each electrode and expressed by a fixed relative equation and the plus-side split electrode group or between the minus-side split electrodes themselves, and then by obtaining the difference of both electrode groups. In plus- side split circuit 20, full electrode n is divided into two groups (N=2). The clock pulse is applied from clock pulse source 3 to the two electrode groups via integral capacity (1/2C<+>1) 211 and 212 and then supplied to the plus input terminal of differential amplifier 5 via MOS22. In general, when the CCD filter is constituted by dividing each of plus and minus electrodes n into N-groups, the N-multiplied large output signal can be obtained via 2N-units of FET.
