ABSTRACT:
A signal output circuit is disclosed that supplies a signal from a first circuit that is driven based on a first reference voltage to a second circuit that is driven based on a second reference voltage. The signal output circuit includes a first control circuit that draws a current to the first reference voltage according to an output signal from the first circuit and supplies a signal to the second circuit according to the drawn current, and a second control circuit that draws a current from the second circuit to the second reference voltage.
