Abstract
An electronic circuit device has a current correction circuit that supplies a correction current which is capable of offsetting an increment or a decrement of a consumption current of a signal processor circuit that varies based on a signal level of an input signal. Therefore, even if the consumption current of the signal processor circuit varies based on the signal level of the received input signal, the variation of the consumption current is offset by the current correction circuit. As a result, even if the consumption current varies based on the signal level of the input signal, since a current that flows in a resistor does not vary, a voltage drop can be held constant. Accordingly, it is possible to accurately conduct a comparison determination by a comparator.
