ABSTRACT:
A circuit for weighted addition which includes a transistor having a gate and a plurality of resistance elements. Each resistance element has a first and second end. The first end of each resistance element is impressed with a voltage, and the second end of each resistance element is connected to the gate of the transistor. The circuit is small in size and renders precise and various types of weighted addition possible.
