Abstract
Systems and methods for temperature coefficient of offset compensation for a resistance bridge are disclosed. In one aspect, one or more current sources are added in parallel to resistance elements within a resistance bridge. The current source(s) may be selectively switched on and adjusted by a control circuit based on readings from a temperature sensor. In this fashion, the temperature induced variations in the resistance may be canceled or corrected allowing for better performance of the resistance bridge.
