Abstract
A method and apparatus for dynamically matching a plurality of resistors to a sensor are disclosed. In the method and apparatus, a switching block of a plurality of switching blocks receives a plurality of selection signals. The switching block is coupled to a resistor array having a plurality of resistors that are coupled in series and arranged in a closed loop. Each two resistors are coupled to each other by a respective resistor node of a plurality of resistor nodes. The switching block of the plurality of switching blocks has a plurality of input nodes and an output node, where the output node is coupled to the respective resistor node of the plurality of resistor nodes. In the method and apparatus, the switching block couples an input node of the plurality of input nodes to the output node based on the selection signals.
