What is the input and output impedance of common collector?
A common-collector (CC) amplifier typically has a high input impedance (typically in the hundred kΩ range) and a very low output impedance (on the order of 1Ω or 10Ω). This makes the common- collector amplifier excellent for “driving” small loads.
What are the input and output impedance of CB configuration?
So for the common base configuration the input impedance is very low and depending on the value of the source impedance, RS connected to emitter terminal, input impedance values can range from between 10Ω and 200Ω.
What is the input impedance of a common collector amplifier?
A common-collector (CC) amplifier typically has a high input impedance (typically in the hundred kΩ range) and a very low output impedance (on the order of 1Ω or 10Ω). This makes the common-
What is the output voltage of a common collector?
The input supply voltage between base and collector is denoted by VBC while the output voltage between emitter and collector is denoted by VEC. In this configuration, input current or base current is denoted by IB and output current or emitter current is denoted by IE.The common collector amplifier has high input impedance and low output impedance.
What are the characteristics of a common collector?
Common collector configuration have high input configuration and low output impedance. It has low voltage gain, high current gain and the power gain is medium. This configuration is mostly used for impedance matching, that is high impedance source is used to drive low impedance load. Input Characteristics of Common Collector Configuration:
What is the name of the common collector configuration?
So input is applied between base and the collector terminals and output is taken from emitter and collector terminals. The common collector configuration is also called emitter follower or voltage follower because the output emitter voltage always follows the base input voltage.
