In a cascade amplifier, two identical or non identical amplifiers are cascaded ,i.e., connected in series through a capacitor. They are mostly common emitter amplifiers that are cascaded together.The final gain of the cascaded amplifier is the product of the first amplifier's gain and the second amplifier's gain. However, the bandwidth of the cascaded version becomes lesser than the individual gains.

Who is more gain amplifier cascaded amplifier or darlington amplifier?
Darlington amplifier has more gain when compared to cascade amplifier .
Why ce configuration of transistor has a 180 phrase difference in output?
A: As current begins to flow the action on a resistance will be a voltage drop which is inversely proportional to the current. Making it a voltage amplifier as opposed to a tube where it is a current amplifier
What is current series feedback amplifier and its uses?
current series feedback amplifier=series parallel feedback amplifier or voltage to current amplifier,or TRANS CONDUCTANCE AMPLIFIER.
What is selective amplifier?
Selective amplifier is an RF amplifier which selects particular frequency and amplifier so it can operate at fixed frequency.
How transistor produce 180 degree phase shift?
In the common emitter configuration, a class A amplifier, an increase in base voltage (the input) leads to an increase in base-emitter current which leads to a proportionately larger increase in base collector current. That pulls the collector towards the emitter, which decreases the collector voltage. Since the collector is the output, this configuration is an inverting amplifier.
Who is more gain amplifier cascaded amplifier or darlington amplifier?
Darlington amplifier has more gain when compared to cascade amplifier .
What the conclusion for cascade amplifier?
Over all feedback
What configuration commonly employed in bipolar transistor amplifier?
Common Emitter - Class A Amplifier.
What is cascade connections?
Cascade connections refers to the series connection of amplifier stages, networks, or tuning circuits in which the output of one feeds. The cascade connection is also known as the tandem connection.
Difference between cascode and cascade amplifier?
cascade: the output of one amplifier stage is connected to the input of another amplifier stages, it's also connected in series. cascode: it said to be cascode, when it has one transistor on the top of another where a common emitter transistor drives a common base transistor.
Need of cascade amplifier?
I dont know exactly... Its may be because we need it!!
What is audio video cascade as it relates to an RCA distribution amplifier?
A Audio Video Cascade on a Video Distribution Amplifier (VDA) is a passive connector that allows the input signal to be passed through unamplified to another VDA. For example, this allows you to connect two four-channel VDA's together to have 8 outputs.
Why it is unsuitable for operational-amplifier to connect in open loop?
In open loop configuration the gain of the amplifier will be infinite, which in turn produces only square wave output.
What if base current is zero in a transistor used as an amplifier with common emitter configuration?
output current is zero
The gain of an operational amplifier will be maximum?
A: the gain will be maximum at the open loop configuration and decrease as frequency increases
What is a function of baising?
what is a function of Biasing and explain it's working ? why the Common Emitter Configuration is use as Amplifier ? Explain in Detail ?
What type of transformer configuration will you select to design a high input impedance and low output impedance amplifier?
main volage
