Single tube amplifier circuit experiment report
I. Experiment Purpose
1. 1. Master the debugging of the static operating point of the single tube amplifier circuit; Familiar with the use of common instruments;
3． Master the main indicators and test methods of the amplifier circuit.
2. Experimental instruments and devices
Equipment conditions: multimeter, oscilloscope, function generator, DC stabilized power supply experimental equipment:
Third, the experimental principle
The basic amplifier circuit has three configurations: common emitter, common base, and common collector. This experiment uses a common emitter amplifier circuit, as shown in Figure 1.1. The triode is a current-controlled current source device (ie, IC = βIB). By properly setting the static operating point, the AC voltage signal can be amplified. The main parameters of the amplifier circuit are voltage amplification factor Au, input resistance Ri, and output resistance Ro.
