A method for temperature equalization of resistors of a resistance measuring circuit as well as resistance measuring bridge circuit and acceleration sensor bridges

摘要

A temperature-compensating method of a resistance bridge circuit constructed of a plurality of resistance devices, comprises: a first step of adjusting in direction and in curvature a temperature characteristic curve of an output signal issued from the resistance bridge circuit in which a resistor for temperature compensation is connected in parallel with one of a pair of the resistance devices, the pair being disposed in adjacent arms of the resistance bridge circuit; and a second step of applying an additional signal to the output signal of the resistance bridge circuit so as to offset the temperature variation of the output signal of the resistance bridge circuit.
