commercial dc-dc converters normally have input range ~1 to 2V. Is it possible to convert a small voltage into a ~3V voltage in applications like wireless sensor?

It's not obvious which previous post you're referring to.Asking about DC/DC converter after IanP answered your previous post and regarding your previous posts is simply another nonsens.

I think that jszar understood what I was talking about.
Precision low drift low noise OpA will do what you need. Asking about DC/DC converter after IanP answered your previous post and regarding your previous posts is simply another nonsens.
Startup of a DC/DC converter at mV input voltages is only possible with a special design, e.g. using depletion mode transistors, and difficult anyway.
Did you calculate the available power from your mV source?
Yes, it's basically a method to design a self-oscillating converter, that has a very low start-up voltage. LTC3108 is using this method.Is the depletion mode transistor you mentioned used as an switch?
