What is a common application of a cc amplifier?
current amplifier
What is one common application of a cc amplifier?
current amplifier
What is the configuration of cascade amplifier?
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.
Why CB amplifier preferred for high frequency than CE amplifier?
1)in cc configuration we use to get the low output impedence where as in ce we use to get the high output impedence. 2)in cc amplifier we use to have the voltage gain equal to unity where as in ce amplifier we use to have the high voltage gain. 3)in cc amplifier there is high power gai which is used for impedence matching where as in ce amplifier due to the high voltage gain the impedence matching is less impossible.
What configuration commonly employed in bipolar transistor amplifier?
Common Emitter - Class A Amplifier.
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 ?
Why phase shift of ce configuration is 180 out of phase while cc has same phase?
In a ce amplifier, an increase of base voltage causes the collector current to rise. This causes an increased voltage drop through the collector load resistor, so the collector voltage drops. With a cc amplifier the increase in current causes more voltage across the emitter load resistor, therefore the emitter voltage rises.
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.
Why the 2n2222 amplifier voltage gain is less than one?
Without knowing things about the circuit that you don't give, this question can't be answered. The 2N2222, as any other bipolar transistor, can give large amounts of voltage gain in both CE & CB configuration, but less than one voltage gain in CC configuration. Nothing is unique about the 2N2222.
The use of swamping resistor in differential amplifier?
the use of swamping resisters in amplifier is in order to protect the amplifier from high temperatures
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
