Marmite spread spectrum sandwich distortion reduction

[Genomerics]

So.... And I'm just blithering here.

Having got bored with trying to analyse what phase/time delay self oscillating things really do and my basic inability to work out how to make them work fixed frequency......

I went back to ChocoHolics hysteretic control. (Are you as handsome as your picture?)

Hmm

First guess almost did the business, of course I'm not going to tell you what it was, but the distortion went up a bit.

Oh.... OK lookit make the hyteresis band....

V=-15*SGN(V(VCMP))*(2500-V(VOUT)*V(VOUT))/2500

If you have +/-50V supplies..... Winky Winky.

Then I tried to nail it and, when I sort of had, all the distortion products went ape.


Lah lah lah..... more investigation required.

At least onions plus reduce and caramalise. Tasty

Anyway, clever people probably know about this dithery spread spectrum blibbly blibble that smears stuff out so you don't notice it.

Like. Innit
