Abstract

PURPOSE:To simplify wirings and make the signal processing high-speed by dividing a channel width correspondingly to a weight coefficient and detecting the charge signal held in this channel by a charge detection part. CONSTITUTION:1 to n in the figure indicate charge transfer electrodes and are connected to common busses B1 to B3 whose number corresponds to the number of drive phases, for example, the number of phases of a 3-phase drive, and the charge injected from source S through gates G1 and G2 is transferred to the output side successively. Then, CS in the figure indicates an electric dam to divide the channel width under the third phase transfer electrodes 3, 6... correspondingly to the weight coefficient, and the charge detection part consists of gate electrode TG and diffusion layers DO to Dm, and diffusion layers are connected to positive and negative input terminals of differential amplifier A, which forms an integration-type amplifier, correspondingly to positive and negative weight coefficients. By this constitution, the complication of wiring patterns can be prevented, and a high-speed signal processing for the direct detection of signal charge can be achieved.
