Electronics tutorial about the common base amplifier configuration where the. Common emitter configuration has both current and voltage gain. Bipolar transistor tutorial, the bjt transistor electronicstutorials. Cb low about 100 ce medium 800 to few k cc high about 750k output resistance input current output current input voltage applied between op voltage taken between current gain voltage gain power gain. Different configurations of transistors common base. The common collector amplifier has high input impedance and low output impedance. Using these 3 terminals the transistor can be connected in a circuit with one terminal common to both input and output in a 3 different possible configurations. Common emitter transistor configuration ce the common emitter transistor configuration is most widely used configuration. Generally there are three different configurations of transistors and they are common base cb configuration, common collector cc configuration and common emitter ce configuration.
In this tutorial we will look more closely at the common emitter configuration using. The circuit of ce transistor gives a medium ip and op impedance levels. The common base amplifier is another type of bipolar junction transistor. These modes are used in various transistor based applications as per characteristics mentioned below. Basic electronics transistor configurations tutorialspoint. Transistors characteristics for cb, ce and cc transistors. Table 2 gives the value of a i, a v, a p, r i, and r 0 for a typical transistor hparameters given in table 1 for all the three configurations using. Any twoport network which is analogous to transistor configuration circuits can be analysed using three types of characteristic curves. A transistor has 3 terminals, the emitter, the base and the collector. In physics, the graph representing the relationships between the current and the voltage of any transistor of any configuration is called transistor characteristics. Transistor circuits use one of three transistor configurations. To fully describe the behavior of a transistor with cc configuration, we need two set of characteristics input characteristics and output characteristics. Common base amplifier configuration electronicstutorials.
Different configurations of transistors common base, collector. The behavior of these three different configurations of transistors with respect to gain is given below. Comparison of ce, cb and cc configurations engineering. Ce, cc, cb configurations, configurations of bjt, common emitter configuration, common base configuration, common collector configuration, common emitter current gain, common base current gain. Different configurations of transistors common base cb, common collector cc and common emitter ce input and output. This page compares cb vs ce vs cc transistor configurations and mention difference between cb, ce, cc transistor modes. It is used as a buffer amplifier between a high impedance source and a low impedance load. The gain of the both voltage and current can be defined as a medium, but the op is opposite to the ip that is 1800 change in the phase. Common collector configuration has current gain but no voltage gain. As we know transistor is solid state equivalent of a triode valve.
