晶体管具有电流放大作用。当发射结正向偏置而集电结反向偏置时,从发射区注入到基区的非平衡少子中仅有很少部分与基区的多子复合,形成基极电流,而大部分在集电结外电场作用下形成漂移电流IC,体现出IB对的IC控制作用。此时,可将IC看成电流IB控制的电流源。 三个重要的电流分配关系式: IE=IB+IC IC=βIB+ICEO≈...
We proceed with our term project, an audio speaker or headphone amplifier. We firstanalyze the bias model for the existing circuit and establish the parameters. Then weincrease the supply voltage form 5 Volts to 12 Volts and re-examine the circuit voltages and bias. Finally we revise the ...

Novel Circuit Model of Small-signal Amplifier Developed by using BJT-JFET-BJT - Shukla, Srivastrava - 2012 () Citation Context ...r response problem at higher frequencies [1]-[4]. A number of modifications in Darlington’s composite unit or in respective amplifier circuits are suggested by ...
However, with the application of a tank circuit (parallel resonant inductor-capacitor combination) to the output, the occasional output surge produced by the amplifier can set in motion a higher-frequency oscillation maintained by the tank circuit. This may be likened to a machine where a heavy ...
