ABSTRACT:
A computational circuit which has a capacitive coupling for weighted addition. Addition is performed by the capacitive coupling. By connecting and disconnecting capacitances of the capacitive coupling, multiplication can be executed by changing the weights of the capacitors. An inverter with a feed back capacitance is connected to a computational circuit to improve the accuracy of the computation.
Capacitances consist of unit capacitances of scattered distribution, so that the deviation of the capacities is minimized.
