ABSTRACT:
A video amplifier includes three amplifier circuits (TR, TG, TB) for the red, the green and the blue signals which are each provided with a different feedback signal which changes value when the signal exceeds a certain threshold, by a feedback resistor circuit having two central junction being connected by a diode (Tth) to a fixed voltage (DZ). The ratio value between the two cascade-arranged resistors is different the resistor at the base of a cascade arrangement of resistors may be common for several amplifier circuits.
