Abstract
In a circuit device for analyzing analog signals from first and second circuits. The first and second circuits are designed to output analog signals which are opposite to each other in the positive and negative signs of phase. When short-circuit occurs, the output signals from the first and second circuits interfere with each other and thus these signals are offset by each other, so that malfunction caused by the short-circuit can be prevented, and also neither a device not a terminal is required to be added.
