Transistor Amplifier Circuit Board. Locate the common base emitter circuit block and connect the circuit as shown in figure 3 2. Transistor amplifiers are grouped into one of three basic circuit configurations depending on which transistor element is common to input and output signal circuits.
Up to 78 efficiency is possible with class ab designs and cross over distortion is reduced. But common emitter configuration is frequently used in the applications like an audio amplifier. An amplifier circuit board is the heart of an amplifier.
4 transistor so 4x1 3 5 2 ampers we can use.
Up to 78 efficiency is possible with class ab designs and cross over distortion is reduced. This gives us a 250 mw amplifier enough to drive a loudspeaker to the same volume as a mobile phone or mp3 player. Hence the output of the voltage divider circuit is used for proper biasing to turn on the. In the above circuit diagram we have made a voltage divider circuit using resistor r1 and r2 of 4 7k and 1 5k respectively.
