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.
Immediate Addressing In this addressing mode that 8/16 bit data is specified in the instruction itself as its one of the operands. Normally the instructions using a
Athree-phase, wye-connected, round-rotor, 220- V, 60-Hz, synchronous motor, having a synchronous reactance of 1.27 per phase and negligible armature resistance, is connected in p

Why is the signal first attenuated and then amplified?

A common-collector (CC) amplifier is also known as an emitter follower (or a voltage follower) due to the fact that the output voltage "follows" the input by being approximately eq
