If you relate the question to power rectifiers, larger cap means higher peak current and thus higher Irms/Iavg ratio, in other words lower current rating.
Okay. Basically I need a large capacitor in the IC that I design. But I don't it to consume the space in my IC. I thought of using Miller Technique to boost the capacitance using an amplifier and a small capacitor but most of the papers suggest that there is a problem in it. Can you tell me what that problem exactly is?

The method works only dynamically, but you can't multiply a static capacitance. In other words: you can use the multiplication effect e.g. to filter AC voltages, but you can't multiply the capacitance to store a larger DC energy.
Hi Dear EriklAdditionnally, larger C has lower ESR.

... i had this problem in many of my designs , when capacity , is larger , ESR is larger too . perhaps your mean was another thing ?

I was reading a paper on implementing rectifier in CMOS technology. I read that a large holding capacitor is needed (at the output) in order to get a high current rating. How do you say that?
The question can't be answered without clarifying the capacitor purpose.Can anyone explain me whether these two statements are correct or either of them are a wrong statement?

Regarding ESR you can't compare a cercap with an Al elco.For example a 100 nf capacitor . and a 4700 uf capacitor .
Sure, for a high cap (4700µF) @ 3MHz and 10A.i think that warming was because of ESL . am i right ?
