Abstract
PURPOSE:To shorten transfer channel length by arranging CTDs (charge transfer devices) into two parallel lines and giving input signal strings alternately to perform storage and transfer by the half clock frequency and adding read and weighted signals to obtain an output. CONSTITUTION:Two lines of delay circuits where delay elements D' dependent upon CTDs are cascaded are provided, and signals at connection points of respective elements D' are led to weighting circuits hO-hN, and their outputs are given to adder circuits SIGMA(1) and SIGMA(2). Selector switch SW operates synchronously with the clock period of input signals and gives input pulses to inputs of both delay circuits alternately. Both delay circuits are controlled by clocks twice as long as the clock period, thus performing storage and transfer.
