Basic electronics transistor configurations tutorialspoint. As we know transistor is solid state equivalent of a triode valve. 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. Different configurations of transistors common base cb, common collector cc and common emitter ce input and output. Common collector amplifier basic electronics tutorials.
Transistors characteristics for cb, ce and cc transistors. Transistor configuration common base, collector and emitter. This type of biasing arrangement is commonly used in the design of bipolar transistor amplifier circuits and greatly reduces the effects of varying beta. The commonemitter ce, commonbase cb, and commoncollector cc configurations, their hybrid. Common base amplifier configuration electronicstutorials. Generally there are three different configurations of transistors and they are common base cb configuration, common collector cc configuration and common emitter ce configuration. Different configurations of transistors common base. The three types of configurations are common base, common emitter and common collector configurations. Common collector transistor configuration cc the common collector transistor configuration is also known as the emitter follower because the emitter voltage of this transistor follows the base terminal of the transistor.
We also learnt that the transistor junctions can be biased in one of three different ways common base, common emitter and common collector. Transistor circuit configurations electronics notes. The following formula is used to calculate the current gain of the ce. Voltage gain of a two port network the hparameters of an ideal cb transistor the hparameters of an ideal ce transistor. The base of the transistor used in a common emitter amplifier is biased using two resistors as a potential divider network. Different configurations of transistors common base, collector. As with the common emitter ce amplifier configuration, the input signal is applied to the transistors base terminal, and as we said previously, the amplifiers output.
This page compares cb vs ce vs cc transistor configurations and mention difference between cb, ce, cc transistor modes. Compare bjt amplifier in ce, cb, cc configurations. The behavior of these three different configurations of transistors with respect to gain is given below. Voltage feedback is used with two resistors between the collector and base and a single voltage source, v cc, or with the same circuitry but adding an additional resistor and reversed biased v bb between the base and ground. Current feedback is the use of a resistor in series with the emitter. Ce, cc, cb configurations, configurations of bjt, common emitter configuration, common base configuration, common collector configuration, common emitter current gain, common base current gain. The common base amplifier is another type of bipolar junction transistor, bjt.
