ABSTRACT:
In a video amplifier including a voltage gain stage and a current-amplifying output stage, feedback is applied from an output to an input of the voltage gain stage. The output stage includes a first current gain stage having a first push-pull amplifier and a second push-pull amplifier. The inputs of each of these push-pull amplifiers is connected to an output of the voltage gain stage. The output stage also includes a second current gain stage having a common-collector NPN transistor and a common-collector PNP transistor, the NPN transistor having its base terminal connected to the output of the first push-pull amplifier of the first current gain stage, and the PNP transistor having its base terminal connected to the output of the second push-pull amplifier of the first current gain stage. The output of the output stage is provided at an output terminal connected to the emitters of the NPN and PNP transistors of the second current gain stage.
