Abstract:
1. A semiconductor integrated circuit device comprising: a first circuit that outputs a first signal which varies between a ground voltage and a second voltage higher than the ground voltage; a first conversion circuit that receives the first signal and that outputs a second signal which varies between the ground voltage and a third voltage higher than the second voltage; a first output circuit that receives the second signal and that outputs a third signal which varies between the ground voltage and a fourth voltage between the second voltage and third voltage; a second circuit that outputs a fourth signal which varies between the ground voltage and the second voltage; a second conversion circuit that receives the fourth signal and that outputs a fifth signal which varies between the ground voltage and the third voltage; and a second output circuit that receives the fifth signal and that outputs a sixth signal which varies between the ground voltage and a fifth voltage between the second voltage and fourth voltage, wherein the first and second circuits are supplied with the ground voltage and the second voltage, wherein the first and second conversion circuits are supplied with the ground voltage and the third voltage, wherein the first output circuit is supplied with the ground voltage and the fourth voltage, and wherein the second output circuit is supplied with the ground voltage and the fifth voltage.
