What is the major difference between CE CB and CC?
Comparison between CB, CE, and CC Configuration
| Characteristics | CB | CC |
|---|---|---|
| Output Current | Collector Current or IC | Emitter Current or IE |
| Output Signal Phase | Same phase with input | Same phase with input |
| Current Gain | Always less than Unity α = IC/IE | Very High γ = IE/IB |
| Voltage Gain | About 150 | Less Than Unity |
What is CB CE and CC configuration?
Common Base (CB) Configuration: no current gain but voltage gain. Common Collector (CC) Configuration: current gain but no voltage gain. Common Emitter (CE) Configuration: current gain and voltage gain.
What is CE CB CC configuration transistor?
Common Collector (CC) Configuration of Transistor In CE Configuration, the Collector terminal of the transistor will be connected common between the output and the input terminals. The variation of emitter current(IB) with Collector-Base voltage(VCB), keeping Collector Base voltage(VCB) constant.
What is CB configuration?
The Common Base Amplifier is another type of bipolar junction transistor, (BJT) configuration where the base terminal of the transistor is a common terminal to both the input and output signals, hence its name common base (CB). That is the base-emitter junction is forward-biased.
How to compare CE, CB and CC configurations?
Comparison of CE, CB and CC Configurations: It is useful to study the variation of A I, A V and R i with change in load resistance R L for each of the three configurations.
When to use CB, CC, CE transistors?
CE configuration is used RF signal processing circuits. 2. This configuration is used for audio amplifier circuits. 3. This configuration is used in sensor controller circuits. This is the most usable and simple configuration of transistors. In this configuration, the collector terminal of the transistor is used as a common terminal.
How is CC configuration used in a circuit?
CC CONFIGURATION In common collector configuration circuit is shown in figure. Here collector is grounded and it is used as the common terminal for both input and output. It is also called as grounded collector configuration. Base is used as a input terminal whereas emitter is the output terminal.
What is the current gain of a CE configuration?
Here you can see the diagram below. 1. This configuration provides very low input impedance (only 50 to 500 ohm). 2. It provides very high output impedance (1 to 10 Mega Ohm). 3. In this configuration, the current gain denoted by alpha which is always less than unity (0.95 to 0.99).
