Answer / ashutosh vikram singh

it offers high o/p resistance and low i/p resistance so
voltage gain=resistance at o/p/resistance in i/p
so voltage gain is high

Answer / praveen

common base current gain. Ic/Ie since Ie =Ic +Ib,
Ie>Ic(from expression)
Therefore not used for current gain.
It has high o/p resistance and low input resistance
hence used as voltage amplifier

Answer / dhruv

Common-base transistor amplifiers are so-called because the input and output voltage points share the base lead of the transistor in common with each other, not considering any power supplies.
The current gain of a common-base amplifier is always less than 1. The voltage gain is a function of input and output resistances, and also the internal resistance of the emitter-base junction, which is subject to change with variations in DC bias voltage. Suffice to say that the voltage gain of a common-base amplifier can be very high.
The ratio of a transistor's collector current to emitter current is called α. The α value for any transistor is always less than unity, or in other words, less than 1.
