| Zusammenfassung: | The utility model discloses a high-efficiency video amplifier. The video amplifier comprises an amplifier unit, first to eighth resistors, a first capacitor and a second capacitor. The inverting input terminal of the amplifier unit is connected to the first terminal of the second resistor and the first terminal of the third resistor. The second terminal of the second resistor is grounded. The non-inverting input terminal of the amplifier unit is connected to the first terminal of the first resistor and the first terminal of the sixth resistor. The second terminal of the first resistor is grounded. The second terminal of the third resistor is connected to the output terminal of the amplifier unit, the first terminal of the first capacitor, and the first terminal of the fifth resistor. By employing the high-efficiency video amplifier, the brightness, chroma and synchronizing signals of videos can be enhanced, interference signals are reduced, and saturation phenomena of the videos are prevented. The video amplifier is simple in structure, is low in power dissipation, and has popularization and usage values. |
