PURPOSE:To improve the precision of a voltage dividing circuit composed of a resistance network and a reference voltage source by adjusting the resistance values of mutual connecting conductors which connect resistors mutually in a specific way. CONSTITUTION:Resistors 11-13 with a resistance value R are connected to a reference voltage source in series. Further, resistors having resistance values R and R/3 are connected in parallel through mutual connecting conductors 16- 18. Then, the values of the mutual connecting conductors 16-18 are so adjusted that when the current flowing through the resistance 11 is I, currents I/2, I/4, I/2, and 3I/4 flow through the resistances 12, 13, 14, and 15. At this time, when the resistance value of the mutual connecting conductor 16 is (r), the resistance values of other conductors 17 and 18 are only adjusted to 2r. Thus, the precision of the voltage-dividing circuit is improved. |
