Abstract:
1. A pulse signal output circuit comprising: a first transistor; a second transistor; a third transistor; a fourth transistor; a fifth transistor; a sixth transistor; a seventh transistor; an eighth transistor; a ninth transistor; and a tenth transistor, wherein a first terminal of the first transistor, a first terminal of the second transistor, and a first output terminal are electrically connected to one another, wherein a first terminal of the third transistor, a first terminal of the fourth transistor, and a second output terminal are electrically connected to one another, wherein a first terminal of the fifth transistor, a first terminal of the sixth transistor, and a first terminal of the seventh transistor are electrically connected to one another, wherein a gate terminal of the first transistor, a gate terminal of the third transistor, and a second terminal of the seventh transistor are electrically connected to one another, wherein a gate terminal of the second transistor, a gate terminal of the fourth transistor, a gate terminal of the sixth transistor, a first terminal of the eighth transistor, and a first terminal of the ninth transistor are electrically connected to one another, wherein a second terminal of the eighth transistor and a first terminal of the tenth transistor are electrically connected to each other, wherein a ratio W/L of a channel width W to a channel length L of the first transistor and a ratio W/L of a channel width W to a channel length L of the third transistor are each larger than a ratio W/L of a channel width W to a channel length L of the sixth transistor, wherein a ratio W/L of a channel width W to a channel length L of the fifth transistor is larger than the ratio W/L of the channel width W to the channel length L of the sixth transistor, wherein the ratio W/L of the channel width W to the channel length L of the fifth transistor is equal to a ratio W/L of a channel width W to a channel length L of the seventh transistor, and wherein the ratio W/L of the channel width W to the channel length L of the third transistor is larger than a ratio W/L of a channel width W to a channel length L of the fourth transistor.
