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.
What do you mean by Bezier curve? Shown B0 (1,1), B1 (2,3), B2 (4,3), B3 (3,1) the vertices of Bezier polygon, calculate seven points on Bezier curve. Write in brief the differe

Personal safety Power supplies can be very dangerous. This is specifically true of high voltage circuits, but anything over 12 V must be treated as lethal potentially. A po
Q. Evaluate complex power in power system? The complex power ¯S in a single-phase systemis the complex sum of the real (P) and reactive (Q) power, expressed as follows:
