Filed: 2000-08-18
Abstract: PURPOSE: A gain correction circuit of a USB(Universal Serial Bus) camera interface is provided to correct the gain lost by an interface cable and an interface board when a USB camera is mounted on a displayer. CONSTITUTION: A gain correction circuit of a USB camera interface consists of impedance matching resistors(R1,R3) connected to a terminal and a cable wafer of a USB interface board to detect the transmission/reception of data clock lines, and plural amplifying transistors(Q1,Q2) for correcting bandwidth. The resistor(R1) is used for impedance matching in using a USB extended cable. If the resistor is not used, interference between a data line and a ground line is generated by current mirror phenomenon to generate ghost in video communication with a camera. The impedance matching signal is amplified into current by the first amplifying transistor. To correct a low clearness caused by lack of current in a data video, a resistor(R2) is operated as an emitter follow-up circuit for buffering of the first transistor. Therefore, the ghost on a monitor is removed and the bandwidth is improved.
