What is the physical significance of infinite open loop voltage gain of an ideal operational amplifier?
Distortion is estimated as closed loop gain divided by open loop gain. If the open loop gain approaches infinity, distortion approaches zero.
If the gain of a non-inverting amplifier equals Rf over Ri plus 1 Then what if Rf equals 0 and Ri equals infinite What is this type of op-amp?
It will have a fixed gain of 1. It is known as a voltage follower or a unity gain buffer.
How gain varies with bandwidth in an op-amp?
The gain of an op amp varies with frequency. After an op amp reaches the half-power point, the gain falls appreciably. And then once it hits the transition frequency, the op amp no longer provides any gain.
What are the properties of an op-amp?
Properties of an op-amp are as follows: 1.Very high open loop gain which remains constant over the frequency range in which the device is to be used. 2.Very high input impedance to minimize the current drawn by the circuit with little losses. 3.Very low output impedance 4. They are stable, i.e. not liable to burst into parasitic oscillation. 5. They are free from drift caused by ambient temperature changes.
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 is the maxium current gain of common base amplifier?
If Beta is infinite, then the current gain will be unity.
Can instantaneous velocity equal infinity?
No, in the physical world nothing can reach an infinite speed, as it would gain infinite mass which is not possible. In Math, you could have the velocity equal infinity for theoretical purposes, but the constant C, the speed of light, would be a better choice.
Why feedback is used in op-amp?
Feedback in used in an op-amp to limit and control the gain. An op-amp, by itself, has very high gain, often more than 100,000. (A theoretical op-amp has infinite gain.) The external feedback loop forms a divider, more correctly a bridge, that is maintained in balance by the op-amp, giving the desired real gain.
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.
What is definition of a simulation in statistics?
a way to model random events, such that simulated outcomes closely match real-world outcomes. By observing simulated outcomes, researchers gain insight on the real world.
Is it safe to set car audio crossover gains to full volume?
When you say car audio crossover gain do you mean the gain on one of your amps or the decible gain you can adjust through your head unit?
What does the OP stand for in OP amps?
Op amps stands for operational amplifier. An operational amplifiers is a high gain voltage amplifier that requires a differential input and produces single outputs.
What is the physical significance of infinite open loop voltage gain of an ideal operational amplifier?
Distortion is estimated as closed loop gain divided by open loop gain. If the open loop gain approaches infinity, distortion approaches zero.
How do you gain fv's on Farmville?
You gain 1 per level or you can buy them with real money.
What are characteristics of an ideal diode?
An ideal diode:Passes current in one direction only. (Under forward bias).Has no leakage current (passes no current under reverse bias).Has no forward voltage drop. (No voltage loss under forward bias - a real diode has Vd~=0.7)See links for more details.
Why open loop gain of op-amp is very high?
A; An ideal op amp should have infinite open loop gain so when the loop is closed with negative feedback it will be stable
What are some advantages of becoming involved in real estate franchise?
A real estate franchise can prepare you for the world of buying and selling real estate. If you choose to be an hourly employees in a franchise you will gain experience, and eventually be able to begin your own franchise.
