Common collector amplifier is on in which the collector terminal is common to both input and output circuit. Following are the some of the characteristic amplifiers of CC amplifier are
Rin = Rb//(β+1)*(re+(ro//Rl))
Av = (ro//Rl)/( ro//Rl+re)
Rout = ro//(re+(Rsig//Rb/(β+1)))
Gv = (Rb/(Rb+Rsig))*( ro//Rl/(Rsig//Rb/(β+1))+re+(ro//Rl)))
Ais = β+1.
