Any confjguration (CB, CE, CC) for active region of operation EB junction forward &CB junction reverse bias. In the case of CC amplifier. It is commonly used for impedance matching (voltage gain <1).

In PNP,
For c-c configuration output is taken against the Emitter terminal so
E - B junction = forward bias.
B-C junction = reverse bias.
For c-c configuration output is taken against the Emitter terminal so
E - B junction = forward bias.
B-C junction = reverse bias.

It was wrong. For any configuration in NPN collector base junction should be reverse bias, emitter base junction should be forward bias.

In case of C-C configuration. The input characteristics at BASE TO EMITTER to forward bias the diode to make the device works properly.

I'm with aje, there no such thing as biasing b/w collector and emitter as there is no junction b/w emitter and collector.

PNP.
For C-C configuration.
The output is taken against the emitter terminal.
B-E forward bias.
B-C reversed bias.
For C-C configuration.
The output is taken against the emitter terminal.
B-E forward bias.
B-C reversed bias.

As it is cc means that collecter is common to both input and output so collecter emmiter will be in forward bias.

It is a common collector config so collector base is reverse biased then collector emitter is forward biased.

Irrespective of configuration, always EB= Forward Bias and BC= Reverse Bias.

@ Aje:.
Its a common collector conf. So collector terminal will be common.
Its a common collector conf. So collector terminal will be common.
