<p>A semiconductor arithmetic circuit which performs calculation of an analog vector with a high accuracy at a high speed. A semiconductor arithmetic circuit which is provided with a plurality of MOSs, wherein the source electrodes are connected to each other and the gate electrodes are connected to a signal line maintained at a prescribed potential through switching elements, and at least one input electrode capacitively coupled with the gate electrodes. First and second input voltages are respectively applied to the input electrodes of at least one pair of first and second MOSs. The arithmetic circuit has a means for equalizing the potentials of the gate electrodes to that of the signal line by allowing the switching elements to conduct. The circuit further has a means for inputting the second and first input voltages to the input electrodes of the first and second MOSs after electrically floating the gate electrodes by breaking the switching elements.</p> |
