Abstract
The present invention provides a voltage difference measurement circuit comprising a level shifting circuit, an ADC and a calculation circuit. In the operations of the voltage difference measurement circuit, the level shifting circuit adjusts levels of a supply voltage and a ground voltage to generate an adjusted supply voltage and an adjusted ground voltage, respectively. The ADC performs an analog-to-digital converting operation upon the adjusted supply voltage and the adjusted ground voltage to generate a first digital value and a second digital value, respectively. The calculation circuit calculates a voltage difference between the supply voltage and the ground voltage according to the first digital value and the second digital value.
