二、计算机分析结果(续) (二)计算机分析结果 1.直流分析结果:直流输入数据中的电源、电阻参数见图1。直流分析时E_2、E_3均取0伏,E_2为外加增益控制电压,E_3为交流信号源。晶体管模型参数分为三类,T_3、T_4、T_8、T_9。作为第一类,横向PNP管T_(15)作为第三类,其余管子均作为第二类。三类管子的直流原始参数见表1,直流分析结果见表2。表2中给出了各个晶体管的集电极、基极、发射极电压,单位为伏,还给出了各个晶体管的基极、发射极电流,单位为毫安。其中T_(19)～T_(25)的集电极、基极相连成为二极管。表中每项均分两种情况:1表示原始输入数据情况(其中R_(12)=350欧,R_(13)=1.04千欧,R_(14)=510欧,R_(22)=520欧),2表示加大第一、第二级中放工作电流情
Second, the computer analysis results (continued) (b) computer analysis results 1. DC analysis results: DC input data in the power supply, resistance parameters shown in Figure 1. DC analysis E_2, E_3 are taken 0 volts, E_2 for the gain control voltage, E_3 for the AC signal source. Transistor model parameters are divided into three categories, T_3, T_4, T_8, T_9. As a first category, horizontal PNP T_ (15) as a third category, the remaining tubes are as a second category. The three types of pipe DC original parameters in Table 1, DC analysis results in Table 2. Table 2 shows the collector of each transistor, base, emitter voltage, in volts, but also given the base of each transistor, the emitter current in milliamps. T_ (19) ~ T_ (25) of the collector, the base connected to become diodes. Each item in the table is divided into two cases: 1 represents the situation of the original input data (where R_ (12) = 350Ω, R_ (13) = 1.04kΩ, R_ (14) = 510Ω, R_ (22) ), 2 said to increase the first and second level in the working current situation
