Abstract
A voltage sensing circuit is provided. The voltage sensing circuit includes two differential amplifiers and a buffer. The first differential amplifier receives a first input voltage and a first reference voltage and provides a first current and a second current according to the difference between the first input voltage and the first reference voltage. The second differential amplifier receives a second input voltage and a second reference voltage and provides a third current and a fourth current according to the difference between the second input voltage and the second reference voltage. The buffer is coupled to the two differential amplifiers. The buffer generates an output voltage based on the first current, the second current, the third current, and the fourth current.
