Transistor common emitter amplifier circuit a
Source: InternetPublisher:他们逼我做卧底 Keywords: Transistor common emitter amplifier circuit bias circuit static operating point Updated: 2021/10/11
The circuit adopts a bias circuit that automatically stabilizes the static operating point and has good thermal stability. The triode
is of NPN type (Iceo is very small). Adjusting the potentiometer RP can change the static operating point .
Figure (a) uses a voltage-divided emitter bias circuit ;
Figure (b) uses the thermistor R. to compensate for changes in operating point.
