WebDec 6, 2024 · So if you happen to select a nicely-high HFE PN2222A transistor (like HFE=200) then you only need to supply 0.1mA base current to saturate it when driving a 10mA collector or emitter load current. For such a transistor, the rule-of-thumb overdrive factor-of-10 is overkill. But woe be to you if HFE is lower, or temperature drops to -55C. WebWhen the BJT is on, current flows around this loop from collector to emitter. When the BJT is off no current flows through this loop. In this loop, the loop through Vin, through RB, and …

WebThis voltage drop across the emitter resistor is in series with the base and of opposite polarity compared with the input signal. (This is similar to a common collector configuration having <1 gain.) This degeneration severely reduces the gain from base to collector.
