Filed: 1993-01-21
Abstract: PURPOSE:To obtain a video amplifier circuit which is capable of taking a large amplitude output even at low power source voltage by comparing the potential of the tip of the synchronizing signal of the output of a video signal or the pedestal part with reference voltage and performing a feedback. CONSTITUTION:The sink chip of the output of the video signal gated by the transistor Q3 at the tip of a synchronizing signal is smoothed in a smoothing circuit 8 composed of a capacitor C3 and a resistance R7. The output of the smoothing circuit 8 becomes DC voltage according to the potential of the sink chip of the output of the video signal. This DC voltage is outputted in a form that it is raised by VBE on the side of the emitter of a transistor Q4. The emitter voltage of the transistor 4 is divided by resistances 9 and 10 and is impressed on the base of a transistor Q5 for comparison. In the transistor Q5, when base potential is impressed, exceeding about 0.6V for a gland, continuity is performed between the collector and the emitter, current flows, and when the potential is below 0. 6V, the current is reduced. Therefore, the current flowing in a resistance R2 changes by the base potential of the transistor Q5 and the base bias of a first amplifier transistor Q1 is controlled.
