Transformer coupling
What else can I help you with?
Does the capacitor coupling gives the higher gain in case of amplifier?
NO. Transformer coupling gives the higher gain in case of amplifer.
Which coupling gives high gain in case of amplifier?
no.transformer coupling gives higher gain
Which coupling gives the higher gain in case of amplifier - a Capacitor coupling b Impedance coupling c Transformer coupling?
transformer coupling
Which coupling gives the higher gain in case of amplifier?
DC coupling on the input/output will always give higher gain because AC coupling involves inserting a capacitor, which adds impedance and augments the signal. AC coupling is sometimes necessary though, for such purposes as eliminating DC offset on the base of a transistor, or eliminating a DC offset in a single supply opamp circuit.
Why transformer coupled amplifier is more efficient than RC coupled amplifier?
an RC coupled amplifier is basically used for voltage amplification , where the circuit currents are quite low. higher currents & voltages would mean more dissipation in the load resistors , which is essentially very lossy . The coupling amplitude to the next stage is ideally the same as the previous stage signal excursion. However if a transformer is used for coupling , both large voltages & current can be handled without incurring the dissipation of a resistive load. Moreover a coupling gain of the transformer primary to secondary ratio is also a bonus. also because of the possiblity of correct impedance matching on the primary & secondary side maximum power coupling is obtained. hence transformer coupling is more efficient in such applications. in high frequency applications transformer coupling , along with tuned circuits as applicable is the choice circuit.
Why you need operational transconductance amplifier?
Usually output of an amplifier is a voltage ,...but in case of Operational Transconductance Amplifier ,Iout (current ) is the output. This feature, makes it useful for Electronic control of amplifier gain .
Who is more gain amplifier cascaded amplifier or darlington amplifier?
Darlington amplifier has more gain when compared to cascade amplifier .
How gain of amplifier can be improved?
The gain of an amplifier can be improved by optimizing its design parameters, such as increasing the transistor's transconductance or using higher-quality components to reduce losses. Additionally, employing negative feedback can enhance stability and linearity while allowing for increased gain. Utilizing multiple amplification stages can also be effective in achieving higher overall gain. Lastly, adjusting the biasing conditions can help maximize the amplifier's performance.
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.
Why noise of Low Noise Amplifier increases if you want to increase gain of it?
That is the case with all amplifiers. The noise floor is always lifted when the gain is increased.
Need of multistage amplifier?
The Gain provided by the multistage amplifier is greater than the gain of single stage amplifier. The gain of the two stage amplifier is the product of the gain of the individual stages.
What is gain on guitar amps?
Gain, usually measured in decibels, is the ratio of output to input power. A more sensitive amplifier will have higher gain settings requiring less input signal.
