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.

Why do we use XRA A instruction The XRA A instruction is used to clear the contents of the Accumulator and keep the value 00H.
NPN BJT with forward-biased: An NPN transistor can be referred as two diodes along with a shared anode. In common operation, the base-emitter junction is forward biased and th
