Abstract

PURPOSE:To obtain a high S/N ratio as desired by increasing the number of the amplifier elements which are used in parallel arrangement. CONSTITUTION:Plural units of amplifier element 5 containing capacity 4 and 6 at the input and output sides each are arranged in parallel; change-over switch 2 and 3 are provided at the input and output sides of element 5 each; and then the information is stored in the capacities of the input side in sequence by switching sequentially switch 2 of the input side with every fixed period. These information are amplified through element 5 each to be stored in capacity 6 of the output side, and then the information stored in capacity 6 are drawn out in sequence by switching sequentially switch 3 of the output side. Thus, a high S/N ratio can be obtained as desired by increasing the number of the amplifier elements which are used in parallel arrangement.
