FIELD: radio engineering, communication.SUBSTANCE: method is realised via summation of current of two control channels, one of which forms a component proportional to current of the reference transistor, and the other forms a component dependent on base-emitter voltage difference of the output and reference transistors. To this end, the device for stabilising collector current of the output transistor includes an additional second current mirror output and a differential amplifier with a low-pass filter.EFFECT: gain stability and protection of the output transistor of the amplifier from overheating.4 cl, 1 dwg |
