Picture 1 shows a FET DC power amplifying circuit. VT1 is the difference amplifying circuit, while VT2 is the constant current differential circuit. And VT5 is electrical level moving circuit made by cascading amplifiers. The source voltage of VT3 is about 0.6 V and VT7 and VT8 are current mirror circuit which is used to aggrandize gain and improve the DC operating point stability. VT6 is the circuit that offers differential current to output terminal.
