Explain What Are The Main Purposes For Which A Common-collector Amplifier May Be Used? |
|
Answer» For a common COLLECTOR amplifier, current gain is as high as for CE amplifier, voltage gain is less than unity, input resistance is the highest and the output resistance is the LOWEST of all the three (CE, ,CC and CB) configurations. This circuit finds wide applications as a BUFFER amplifier between a high impedance source and a low load.
