Abstract

PURPOSE:To enable high-speed driving and variable weighting by improving linearity by improving transfer efficiency by adding respective output signals of multipliers which each multiply the output signal of a charge transfer element by a weighting coefficient. CONSTITUTION:An output signal from a tap terminal 24-k is multiplied by an external weighting coefficient Wk at a multiplier 26-k, whose output signal is added to other output signals by an adder 27, so that the sum appears at a terminal 28. Therefore, the output signal of a tape circuit 23-k is led to more than one circuit, and output signal processing is carried out simultaneously by more than one circuit. The tap circuit 23-k is a signal detecting circuit consisting of a floating diffused layer, and a reset transistor buffer circuit, so a delay signal with superior linearity is obtained.
