Deal All,

I am looking for any 1-V operation amplifier or sigma-delta modulator
chip, could you give me some hints?


Thank you very much.

The LM10 was Robert Widlar's early low-voltage opamp, rated at 1.1V,
but good for down to 1.0V supply, at low output currents and if used
at temperatures of 25C or above.

On Semi advertises their new NCS2001 as a 0.9V rail-to-rail opamp.

And there are a number of papers describing 1V or sub-1V circuitry.
Boki, when you find them, perhaps you can give us a nice list. :>)

Thanks,

There are step-up switching reguators that work with 1V input, and
that's all I need to know. :)

Apply a regulator in cell phone, PDA or ?


dislike SOC?

Sorry, I lost the mail, I reply by this one.

Ya, of course, you are right ex, SOSCSDM, but I wish to know is there any
products design by this, or some companies [not academic] doing these kind
of research.

Thanks a lot.

Boki.

Yea, but sometimes you want a tiny circuit with just one op-amp, putting
in a switcher would double the component count...

After checked them, they seems not supplied by 1.0V...
