Claim 9:
10. The line driver according to claim 7, wherein the second comparator comprises:
a first N-type transistor, wherein a first terminal of the first N-type transistor receives the voltage on the output terminal; and
a second N-type transistor, wherein a first terminal of the second N-type transistor is coupled to a control terminal of the first N-type transistor and receives the output voltage, a second terminal of the second N-type transistor is coupled to a second terminal of the first N-type transistor so as to generate the second reference voltage, and a control terminal of the second N-type transistor is coupled to the first terminal of the first N-type transistor.
