Differential mode converter, and measuring device including differential mode converter

A measuring device comprising:

• a target resistance whose resistance value is to be measured;
• an input mode converter configured to convert an input voltage transmitted through the target resistance in a single-ended mode into a first differential voltage and a second differential voltage to be output, the first differential voltage and the second differential voltage being symmetric with respect to a reference voltage and having a form of a square wave;
• a chopper configured to receive the first differential voltage and the second differential voltage and determine a first chopping voltage and a second chopping voltage based on the first differential voltage and the second differential voltage to output the first chopping voltage and the second chopping voltage, the first chopping voltage and the second chopping voltage being symmetric with respect to the reference voltage and having a form of a DC voltage;
• and
• an analog-to-digital converter configured to perform an analog-to-digital conversion on the first output voltage and the second output voltage to output a digital signal based on the resistance value of the target resistance.
