What is the voltage gain of current amplifier?

Janaa kartiwat s The voltage gain of a current amplifier..??? wat can we do to get some current gain with voltage gain unity???

Come on current amplifiers are buffer circuits used to increas e the power at the output.

They must have unity voltage gain at all time

To know more read articles related to Buffer circuits or common collector amplifier CC is the most basic buffer amplifier.

To get current gain alone in a AC signal use CC that is more than enough if noise is tolerable. Other wise go for Mos buffers
