PURPOSE:To reduce remarkably the scale of a circuit by deciding majority decision of 2 binary codes processing it in analog way. CONSTITUTION:Binary codes to be majority-decided supplied to input terminals IN-1-IN-n are supplied to a corresponding inverter of an inversion circuit 1 consisting of (n) units of MOS inverters the same in characteristic, and supplied to the first adder 2 and an inversion circuit 3. The former consists of (n) units of resistors having equal resistance value R, and added through corresponding resistors, and voltage e0 is applied to the terminal (a) of a comparator 5. The latter is the same circuit with the inversion circuit 1, and after inversion, added by the second adder 4 which is the with the first adder, and voltage -e0 is applied to the terminal (b) of the comparator 5.
