The right hand side of C2 should connect directly to the transistor base, not power.I am trying to amplify the ac input signal but any input value results in 0V output, Can anyone what's wrong with my circuit? I don't want to use a voltage divider bias configuration.
I suspect that if you actually knew how the one you don't know how it works, you would have not started this thread.Guys Thanks for all your replies. Really appreciated.
atferrari why I don't want to use voltage divider bias is because I want to test fixed bias configuration first.
Second I identified the mistake myself later and corrected the circuit and it finally worked with some different values.
Is there any book available that precisely focuses on circuit explanation? like what each component does etc
not just the basic theory.
Comment 1: "Different base-emitter voltage"? A transistor does not "have" such a voltage. The base-emitter voltage Vbe is applied externally - and it has a certain relationship to the emitter resp. collector current as defined by the well known exponential formula (which, however, is remarkably temperature sensitive).The first thing I was taught about biasing a transistor is to never simply use one base resistor to a supply voltage.
Because each transistor has a different current gain and has a different base-emitter voltage even if they have the same part number.
Also, the current gain increases as the transistor heats up.
Therefore a voltage divider biases the base plus an emitter resistor is added to 0V.
Sometimes a biasing resistor is connecting between the collector and base for negative feedback.
