Re: Noise Isolation
yah that is correct, but what i mean to ask you is.
For suppose I am doing one PLL. In that I have 4 different power supplies.
AVDD33, AVDD25, AVDD18, DVDD. In this case I can't really use the one substrate connection to all the internal blocks right?
If I do like that, Definetly circuit engineer will cry.
He says my circuit woudn't work. Bcoz you are giving source diffrent and bulk different supplies. Yah it's correct only. Bcoz all the power supplies are not with same voltage levels. From my understanding we should have same number of Substrate power supplies too. Then only we can maintain the same supply to source and bulk. Is this correct or no ?
And coming to width, what ever you said is correct.
But my question is we should have some percentage of width from the original right.
I mean if designer says, I don't mind with the width of the bulk power. I only see for the source power, something like that.
What we can do ? By our knoloedge how we can put. How we can trade off that one.
