Post-fabrication soft trimming of resistive sensors

Abstract : A compact and efficient architecture is introduced as an alternative to laser-trimmed precision thin-film resistor. The purpose is to compensate for process-induced offset in Wheatstone bridges and to avoid the then-obtained degradation in terms of full-scale, non-linearity, power supply noise rejection... Expected advantages are a reduced cost due to the fully-electrical implementation and, depending on the programming technology, a possible re-calibration of high-end sensors.
