PURPOSE:To provide a time division type analog divider which has high accuracy, and also, can be operated by a single power supply. CONSTITUTION:An input EX corresponding to a divisor is inputted to a CR integration circuit 10 through a switch 1b, and its output is inputted a comparator 3 having a hysteresis characteristic having prescribed level width against a certain reference voltage Eref. By an output of this comparator 3, an ON time T1 in a switching period T of switches 1a, 1b is determined, an input EY corresponding to a dividend is inputted intermittently to a smoothing circuit 2 through the switch 1a and averaged, and the quotient EY/X is obtained in the output. |
