由于射极跟随器与源跟随器能够实现阻抗变换作用并提高放大系统的温度稳定性,因此在电子测量仪器中获得广泛的采用。尤其在电子测量仪器的输入端经常是必不可少的。然而,要设计一个比较好的跟随器却并非容易的事情。最难办的问题是: 随着电子测量仪器使用频率的提高,跟随
As emitter follower and source follower to achieve impedance transformation and improve the temperature stability of the amplification system, it is widely used in electronic measuring instruments. Especially at the input of electronic measuring instruments is often essential. However, it is not easy to design a good follower. The most difficult problem is: With the use of electronic measuring instruments to improve the frequency, follow
