Look, this is the gyrator by definition. Got it?

Capacitance multiplier is also referred to as a gyrator.

Concerning my quiet supply circuit for loads requiring low Z posted above, C6 and C7 values are to be defined experimentally with the actual load circuit.

Good for you – it saves you money on audio gear.
I'm not that fortunate.

Nor am i. My amps, not being particularly "engineered" sound wildly different.

Published designs is one thing.
The way they sound may be a different thing.

If you wiggle your big toe, you can feel your pylorus.

 

[alansawyer]

I know what you mean! 🙂

But the real question is, "does the Heisenberg Uncertainty Principle apply in a chrono-synclastic infundibulum?"

It is universal AFAIR ;-)

Joshua, stop, you are killing me Do you have any idea what a gyrator is?

Joshua, you were amusing me but it has got to the point of boredom. Please go somewhere and do some real learning and come back when you have re-read all that you post. You will hopefully learn from that and stop embarrassing yourself.

I wouldn't bother to reply, but some sort of civic duty feeling makes me though raise the :bs: flag.

Congratulation, you just designed an AD797 based oscillator. Due to the opamp loading by the feedback network (120ohm), the AD797 will go very hot and it's unlikely it will survive for long.

That's a good one.
Please go on.

Someone with stinosis need not wiggle anything.

"Gyro" izza Greek for "turn", like This
A mule may look like a donkey but Reverse is not the same as Multiply.

Thank you very much.
You shine.

If this all you can come up with...

BTW Just R2 = 1K alone produces 4 nV/sqrt Hz, and together
with the 100n capacitor, there is a -3 dB corner of 1600 Hz.

Perhaps you should use a pocket calculator and calculate
the very basic facts - instead of applying no-brain mutations
to your dysfunctional circuit and put social pressure upon JC
& the others to correct it.



JC must feel quite uncomfortable. Clap from unqualified friends
can hurt more than a frontal attack.

You excell.

We will see once I'll build it.
Should it need amendments, it will be amended.

 

[jacco vermeulen]

excell.

Even with me forgetting to mention that pyloric stinosis makes one throw up really violently ?
Cool.

Thank you very much for your complements, which are highly appreciated.
We will see how the circuit works once I'll build it.
Should it need amendments, it will be amended.

BTW, do you have a better circuit?

Yes.

 

[jacco vermeulen]

Not meant as a compliment nor as an insult.

It's just that you give the impression of someone who reads from a pathology 101 book each time he visits his MD.
I figured i might as well add some sphincter talk.

To mis-quote Arthur Wellesley the Duke of Wellington, for Joshua_G it is not "publish and be damned" but probably "build and be damned"
