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.
Explain multimeter A multimeter, or universal instrument, may be used to measure voltage, current and resistance.
Q . Why CE Configuration is widely used in amplifier circuit? The main utility of a transistor lies in its ability to amplify weak signals. The transistor alone cannot perform
how started the use of complex variables in circuit analysis for the first time.

Explain Diffusion. Diffusion : Though, the mobility of the carriers in a semiconductor is greater than the electrons in metals, the conductivity in the former is much less t
Define Flash Analog to Digital Converters? Parallel flash ADCs transform the analog input voltage faster as compared to other types of ADCs. They compare the voltage in parall
V- I Characteristics The operation of the diac can be explained by imagining it as two diodes connected in series. When applied voltage in either polarity is small ( less t
Design a recycling MOD 19 up counter using JK FFs. In your design, include the logic circuit diagram and the timing diagram output that counts from 000002 = 010 to 100112 = 1910. C
Sub Threshold The sub threshold I-V curve depends exponentially on the threshold voltage, introducing a strong reliance on any manufacturing variation that influences threshol
Q. The current through a 2.5-mH indicator is a damped sine given by i(t) = 10 e -500t sin 2000t. With the aid of MATLAB, plot the waveforms of the inductor current i(t), with v
