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.

LIFO (Last In First Out) stack is used in 8085.In this type of Stack the last kept information can be retrieved first.
(a) What are the elements of Flexible Manufacturing Systems? (b) What are the basic types of workstations typically found in an FMS. Describe them briefly?
Q. Explain a common emitter configuration without a feedback. A simple common emitter transistor amplifier--having no negative feedback--is not an ideal amplifier. This is beca
Define Hysteresis Hysteresis is the 'lagging' effect of flux density B whenever there are changes in the magnetic field strength H. When an initially unmagnetized ferromagnetic
