<p><P>PROBLEM TO BE SOLVED: To miniaturize capacitor capacitance used in a video signal output circuit provided with a sag correction circuit. <P>SOLUTION: The current source circuit 101 of a clip circuit 212 is configured to make an output current of a voltage/current conversion circuit 53 flow between the base and ground of a third transistor 13 through a second current mirror circuit 52 and a first current mirror circuit 51, the operation range of the clip circuit 212 depends on a power supply voltage, and thus the capacitor capacitance used in the video signal output circuit can be miniaturized. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
