A Darlington amplifier consists of two bipolar junction transistors (BJTs) connected in a configuration that allows the current amplified by the first transistor to drive the second transistor. This arrangement results in a very high current gain, as the output current of the first transistor becomes the input current for the second. The input signal is applied to the base of the first transistor, which greatly amplifies it before passing it to the base of the second transistor for further amplification. The overall effect is a significant increase in both current and voltage gain, making it useful in various applications where high gain is required.

What is the advantage of the darlington arrangement for the CC amplifier?
The Darlington arrangement in a common collector (CC) amplifier provides high current gain while maintaining a relatively low input impedance. This configuration consists of two bipolar junction transistors (BJTs) connected in such a way that the current amplified by the first transistor is further amplified by the second. This results in a significant increase in overall current gain without sacrificing the linearity or bandwidth of the amplifier. Additionally, the Darlington pair can drive heavier loads due to its ability to provide higher output current.
What is the difference between an amplifier and a speaker?
The subwoofer is the actual speaker making the loud bass. The amplifier is what powers the subwoofer and makes it work how it does. It only uses the low frequencies from the audio source and amplifies it.
Circuit diagram for darlington pair transistor?
A Darlington pair is two transistors connected to give a very high current gain
Can negative feedback amplifier work as a oscillator if yes how if no why?
All negative feedback systems, whether they be electronic, biological, or anything else, work by applying a negative feedback to the source signal, which is proportional in some way to the source signal. If the factor by which the amplifier corrects is high enough, oscillation will result (perhaps even runaway oscillation) How you make it happen depends upon the amplifier you use however -- though most work similarly enough. You could use a delay between output and feedback, or you could rely on a large amplifier gain.
What is a Darlington IC?
Darlington circuit is voltage follower circuit with high input impedance and low output impedance.Darlington IC must have this ciruit integrated on it..

Is the audio-source 310 amp direct-coupled?
No. It uses triple-Darlington amplifier stages, and has a rated frequency response only down to 10Hz. It cannot amplifier 0Hz (DC) inputs.

What is bootstraping in darlington emitter follower?
Connecting a resistance btw the o/p and i/p of the amplifier to increase the i/p impedance is called bootstrapping..
What does an amplifier do for a subwoofer?

How do darlington transistors work?
A Darlington transistor it may contain one or more transistor in its case. the purpose is to amplify current by beta multiplication.
Will an unpowered subwoofer work when plugged into an amplifier?
A passive sub-woofer does work when plugged in to an amplifier. In an active sub-woofer ("powered") the amplifier is built in.
