Q Explain about 'Darlington Amplifier'?
DARLINGTON AMPLIFIER : A CC stage followed by another CC stage has an input resistance of about (b + 1) 2 times the emitter resistance of the second stage. More precisely, using the b transform, it is
If RE1 is removed, the second term is about b2 times RE2. Furthermore, if the collectors are connected together, the result is a Darlington stage, as shown below.
This stage can be viewed as a "Darlington transistor" because it has three terminals and an equivalent b of about b2 . Darlington BJTs can be used in any of the three BJT configurations.
Using the LM741operational amplifier build a voltage amplifier with the voltage gain of |A V | = 500 v/v ± = 20%. Measure all necessary parameters of the amplifier (as per deliver
