  • Patent number: 12044715
    Abstract: Aspects of the present disclosure are directed to a measurement module for measurement of a multi-electrode resistive sensing element with improved noise performance and accuracy. In some embodiments, stimulation to the sensing element is provided by a current path that originates from a signal source, through a switch block, through a pair of terminals, and ending at a reference node such as ground. An analog-to-digital converter (ADC) is coupled directly to one or both of the terminals to digitize a voltage. The ADC is coupled to terminals on the sensing element to measure a sensed voltage signal before the sensed signal goes through the switch block. As a result, the measured voltage signal may be free of noise that could be picked up from passing through the switch block, and accuracy of the resistance measurements on the sensing element can be improved.
