摘要

PROBLEM TO BE SOLVED: To provide a reference voltage generating mechanism wherein the space can be reduced by using a simple constitution and reference voltage of high precision can be provided in each gradation, a design method of the reference voltage generating mechanism and design equipment of the reference voltage generating mechanism.;SOLUTION: Resistance elements 20 whose electric characteristics are uniform are used for dividing resistance, and resistance values of each contact 10 and each protrusion part 11 are made minute. Distances between both ends of the resistance elements to which ends a prescribed voltage is applied and each of the contact 10 and the protrusion part 11 are adjusted, and a voltage of a prescribed value is generated. At this time, a resistance element C including a bent part is formed on a prescribed portion of the resistance element 20 if necessary, in order to arrange the resistance element 20 in a range of arrangement region width Wr. In this case, resistance value of the resistance element C is calculated by using a correction coefficient obtained from actual measurements of resistance value of the bent part.;COPYRIGHT: (C)2003,JPO
