    Hi,

    I am a newbie and i am studying BJT circuits. I observed that all the biasing circuits are for Common emitter.Why aren't there any biasing circuits(fixed bias,collector to base bias and voltage divider bias) for common base and common collector.I know that common emitter is used the most everywhere and hence more stress is given on CE circuits.But then I am unable to draw a CB and a CC with all the three biasing circuits.I am obviously missing a very simple point but i don't know where.

    The topology of a biasing circuits does not matter, you can use all the biasing circuits for all BJT amplifiers topology.
    Except "collector to base bias" for CC amplifier. Becaues in CC amplifier we don't have Rc resistor
