Abstract:
1. A resistance bridge measurement circuit configured to be coupled to a first resistor and a second resistor, the first and second resistors being coupled in series, comprising: a current source coupled to the first and second resistors; a first voltage measurement circuit and a second voltage measurement circuit, the first voltage measurement circuit being configured to measure a first voltage across the first resistor and the second voltage measurement circuit being configured to measure a second voltage across the second resistor, the first voltage and the second voltage being measured at substantially the same time; and one or more switches selectively configurable to couple the first voltage measurement circuit across the second resistor to measure a third voltage across the second resistor, and to couple the second voltage measurement circuit across the first resistor to measure a fourth voltage across the first resistor, wherein the third voltage and the fourth voltage are measured at substantially the same time.
