Stress-insensitive diffused resistor network for a high accuracy monolithic D/A converter

Abstract

The stress-insensitive configuration of a Ladder network for a high accuracy monolithic D/A converter is described. To avoid the piezoresistance effect, a stress-insensitive crystal axis is found from the result of the new stress analysis using simple resistors as a strain-sensitive device, which is shifted by 45° from a conventional axis on a surface of
