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.
Switched Mode Power Supply (SMPS) Switching mode power supply converts an unregulated DC voltage to a regulated DC output voltage . SMPS stands for switched mode power
Ac power has significant practical advantages over dc power in generation, transmission, and distribution. One major drawback of the single-phase circuit is the oscillatory nature
For Parity Flag PRE ( Return on Parity Even) and RPO ( Return on Parity Odd) Instructions RPE returns from the subroutine to the calling program if parity flag is not s
Draw the phasor diagrams for an RLC series circuit supplied by a sinusoidal voltage source with a lagging power factor and a GLC parallel circuit supplied by a sinusoidal current s
Q. Explain Common emitter configuration? Common emitter configuration: In this circuit the emitter is common to both input and the output.Such a configuration is also known as
Guarding Against Loss in Transformers Distribution transformers are expected to convert up to 95-98% of the input power into usable output power. A distribution transformers i
(a) Now consider a typical open-wire transmission line with parameters of R = 14 /mi, L = 4.6 mH/mi, C = 0.01 µF/mi, and G = 0.3×10 -6 S/mi. If the line operates at 1 kHz, find t
Insulators have (A) A full valence band. (B) An empty conduction band. (C) A large energy gap. (D)All the above. Ans: Insulators have a large energy gap.
