Gain of transistor
WebBipolar Transistor CHAPTER OBJECTIVES This chapter introduces the bipolar junction transistor (BJT) operation and then presents the theory of the bipolar transistor I-V characteristics, current gain, and output conductance. High-level injection and heavy doping induced band narrowing are introduced. WebEach transistor is a general-purpose amplifier with a standard EBC pinout. PN2222 (same pinout as the 2N3904) can switch up to 40V at peak currents of 1A (not continuously, just peak!), with a DC gain of about 100. PN2907 can switch up to 60V at peak currents of 600 mA (again, not continuously, just peak!), with a DC gain of about 100.

They are PNP and NPN which means an N-type material between two ...
WebThe only way we can get the transistor to reproduce the entire waveform as the current through the speaker is to keep the transistor in its active mode the entire time. This means we must maintain current through the base during the entire input waveform cycle. Consequently, the base-emitter diode junction must be kept forward-biased at all times.
