WebJul 17, 2015 · But if the collector is shorted to the base it can't go much lower than 0.7. You can quibble that 0.6 is different than 0.7, but the point is the same. Less than around 0.7 and the transistor is turning off. So it stabilizes at a collector voltage and current that provides a stable operating point, behaving much like a diode.
WebGenerally speaking, transistor biasing involves applying a specific amount of voltage to a BJT’s base and emitter terminals, improving its efficiency and performance. In this case, the process enables a transistor to amplify an AC input signal in a transistor circuit.
