If AB ->1 the equation Vout = A/(1-AB) goes to infinity based on the math. How is that explained. What controls the change of AB when AB > 0 during startup and AB=1 at steady state. I like the way you analyze circuits.
@ALLABOUTELECTRONICS

In the oscillator, there is no input. So, Vin =0. And still, we are getting finite output. And that is only possible in the system when AB= 1. In the video, like I said, the noise will act as input to the oscillator. So actually there is a very small input (in microvolts or even smaller). And as close loop system point of view, it can be said that this very small input will see a very high gain (ideally infinite), which will build up the oscillations. Initially, the gain provided by the amplifier will be such that AB >1, (And actually it can be set by setting the gain of the op-amp). And when the signal reaches some finite voltage then gain provided by the amplifier will change (Due to non-linearity of the amplifier). e.g, if the transistor is used as an amplifier then for the small input it provides very high gain, but as soon as input signal builds up, transistor goes towards saturation, and in saturation, the gain of the transistor will be different. So, this non-linear behavior of the amplifier maintains the loop gain to unity. I hope it will clear your doubt.

Hi , I have a question . Previously we explained like oscillators are not taking any input and works with thermal noise available in the amplifier circuit. I believe , thermal noise used to have multiple frequency wave from. But here my question is :First block diagram tells that , Oscillators are going to take DC input signal ( How thermal noise is related with DC input signal ) .. Don't able to understand.

It will be superimposed in the DC signal as well. The thing is it is very small in amplitude. But due to positive feedback it will get amplified and eventually a particular frequency component will get amplified. I hope it will clear your doubt.

This disregarded the impulse created by power up conditions for initiating oscillation. This circumstance far outweighs any thermal noise. It also disregards different output waveforms that can be achieved by what the video shows as sinusoidal circuits. Waveform conditioning can also be accomplished by circuits following the oscillator.

Respected Sir, how is the output Sinusoidal? That is why I came. Do we have proof that the internal noise is "sinusoidal"? So then its amplification by A is also sinusoidal and Beta=1/A in feedback once again puts it back equal in magnitude and phase. OR is it so that both the amplifying blocks are frequency selective? Afterall any signal can be reproduced by addition of n different sine waves. So from the chaotic non sinusoidal internal thermal noise, only a particular frequency is favored by A block. Sorry for making it longer. 5:23 I would like to differ. I think it is the A amplifier block which 'must' be frequency selective as the output of A amplifier is the output of circuit itself.

@ALLABOUTELECTRONICS
@ALLABOUTELECTRONICS 15 күн бұрын
It indicates that the closed loop gain is infinite. That means even if there is no input ( ideally) or very very small input, then also we should get output. In oscillators, actually a thermal noise gets amplified by this closed loop gain at some frequency and because of that we are getting oscillations of specific frequency at the output.

Because initially, the input is zero. In reality, the noise acts as an input. And to amplify that noise which is very small in amplitude, you require a very large gain. Theoretically, the input is infinitesimally small and to amplify it you require infinite gain. I hope it will clear your doubt.

@@ALLABOUTELECTRONICS so if initialy is input is zero as u said then Vin becomes 0 (as Vin is input voltage) then Vo =Vin(A/1-AB), output Vo also become zero as per equation, then there is no oscilation at all.
