ABSTRACT:
An electronic circuit device decreases dispersion in the output of the circuit caused by changes in the resistance of the resistors resulting from stress. Resistor positions are selected on the circuit board so that a change in the circuit output caused by a change in resistance of a first resistor group becomes equal to a change caused by a change in resistance caused by a second resistor group, these changes being in opposite directions so as to cancel each other. Alternately, a plurality of resistors are connected to form a composite resistor such that the effect upon resistance of the composite resistor caused by the resistor having decreased resistance is cancelled by the effect upon resistance of the composite resistor caused by a resistor having an increased resistance.
