ABSTRACT:
Disclosed herein is a subtractor circuit for outputting an output voltage as a difference between a first input voltage and a second input voltage. The subtractor circuit may include a first semiconductor element, a second semiconductor element, a third semiconductor element, a fourth semiconductor element, a fifth semiconductor element, and a sixth semiconductor element configured to each invert a voltage input to an input terminal and output the inverted voltage from an output terminal; an input terminal of the first semiconductor element; an input terminal of the second semiconductor element; an output terminal of the first semiconductor element; and an output terminal of the third semiconductor element.
