Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of amplifying circuit, comprise power supply VCC, resistance R b, resistance R s, resistance R e, capacitor C 1, capacitor C 2 and triode VT, resistance R s is connected with one end of capacitor C 1, the other end of capacitor C 1 with the base stage of triode VT, one end of resistance R b be connected, collector electrode, the power supply VCC of the other end of resistance R b and triode VT are connected, the emitting stage of triode VT with one end of capacitor C 2, one end of resistance R e be connected, the other end ground connection of resistance R e.
Described resistance R b is 2K.
Described resistance R s is 1K.
Described power supply VCC is+12V.
Described capacitor C 1 and capacitor C 2 are 1uF.
The course of work: input signal is inputted by the base stage of triode VT, and resistance R e is connected on emitter.Voltage gain is less than 1 but be approximately equal to 1, output voltage and input voltage same-phase, and input resistance is high, output resistance is low.Although the voltage gain of common collector amplifying circuit is less than 1, but its input resistance is high, when signal source offers the onesize signal voltage of amplifying circuit, owing to thering is higher input resistance, the required electric current providing is reduced, thus the load that has alleviated signal source.
