Abstract

PURPOSE:To secure the free setting of the positive and negative weight coefficients by providing the two sets of the input weighting means featuring the variable charge storage capacity and opposing to the input signal and the inverse input signal to each step. CONSTITUTION:Input signal vin receives piling of bias voltage VB and is then applied to signal charge implanting means 12 of one side of each step via terminal 11, and inverse input signal Vin also receives oiling of voltage VB to be applied to signal charge implanting means 12' of the other side via terminal 11'. Either one of these signals is selected via electrodes 13 and 13' corresponding to the switches and then supplied and stored into variable capacities 15 and 15' via electrodes 14 and 14' corresponding to the samplers to be then delivered to the charge transfer elements via electrodes 16 and 16' corresponding to the samplers. Capacities 15 and 15' are varied by control voltage Vhk and V'hk supplied through terminals 17 and 17'. Accordingly, the charge sent to the charge transfer elements is selected for its signal polarities via electrodes 13 and 13' and then receives the gain control via voltage Vhk and V'hk.
