我们设计了一种新的“多功能晶体管放大器实验装置”,学生可以在一次实验中,完成三种基本放大器以及反馈放大器实验内容。还可对它们的性能进行比较分析,从而全面地掌握它们的性能,大大节省实验时间,提高实验效果。下面说明该实验装置的电路结构原理及功能、使用方法。1 电路组成及原理 整个实验装置如附图所示。T为3DG6晶体管,S_1,S_E,S_C,S_L为联动单刀三掷测试电路选择开关,每个开关的1,2,3档分别使电路组成晶体管共射极基本放大器,共基极基本放大器和共集电极基本放大器。K_1为单刀三掷开关,用以控制信号源以不同方式给放大器输入信号(R_0为输入电流取样电阻),当K_1置
We designed a new “multi-functional transistor amplifier experimental device” in which students can complete three basic amplifiers and feedback amplifier experimental content in one experiment. Their performance can also be compared and analyzed to fully understand their performance, greatly saving experimental time and improving experimental results. The following describes the circuit structure principle, function, and method of use of the experimental device. 1 circuit composition and principle The entire experimental device as shown in the figure. T is a 3DG6 transistor. S_1, S_E, S_C, S_L are linkage single-pole, three-throw test circuit selection switches. The 1, 2, and 3 files of each switch make the circuit to constitute the transistor common emitter basic amplifier, and the common base amplifier and the common Collector basic amplifier. K_1 is a single-pole, three-throw switch that controls the signal source to input signals to the amplifier in different ways (R_0 is the input current sampling resistor) when K_1 is set
