f the main group into a part, VT6 a common emitter voltage of the amplifier, the output signal is amplified by the collector. Input by the input signal VI2 base electrode, the collector and base of VT1 VT2 short-circuits to the base of a DC bias, VT4, VT5 the emitter resistor circuit composed of VT2, VT3 collector-bias. Use transistor may reduce the resistance power loss can be obtained the desired amplification effect.
