发明名称 VIDEO SIGNAL OUTPUT CIRCUIT AND SEMICONDUCTOR INTEGRATED CIRCUIT INCLUDING THE SAME
摘要 A video output circuit that is operated at a low power supply voltage and capable of achieving reduced power consumption with a simple circuit configuration and a semiconductor integrated circuit incorporating the same are provided. The video signal output circuit includes a video signal input terminal 1, a clamp circuit 3 that is connected to the video signal input terminal 1, a voltage-current conversion circuit 4 that is connected to the clamp circuit 3, a current amplifier circuit 5 that is connected to the voltage-current conversion circuit 4 and a video signal output terminal 6 that is connected to the current amplifier circuit 5, wherein a resistor 8 is connected between the video signal output terminal 6 and a ground, a transmission line 9 is connected with the video signal output terminal 6, and a load resistor 10 having an equal resistance to the resistor 8 is connected between another end of the transmission line 9 and a ground. The clamp circuit 3 fixes a negative signal voltage.
