ABSTRACT:
A carry-look-ahead adder is provided which is implemented as a semiconductor integrated circuit. The integrated circuit includes a bipolar transistor coupled to the output terminal for providing an output indicative of the arithmetic operation. Impedance elements are coupled to the bipolar transistor and at least one FET is provided to control the on/off state of the bipolar transistor.
