    Abstract: An electronic circuit is provided. The electronic circuit includes a first current generating circuit configured to output a first operating current based on a first operating voltage; and an input circuit configured to: receive a first current corresponding to a first input voltage and a second current corresponding to a second input voltage, wherein the first current and the second current are based on the first operating current; receive a third current and a fourth current that are generated based on the first operating voltage; and generate a fifth current corresponding to the second input voltage based on a second operating current. The electronic circuit is configured to generate an output voltage that is associated with a difference between the first input voltage and the second input voltage based on the second current, the fourth current and the fifth current, and the fourth current corresponds to the third current.
