What is this circuit?

    Apparently its a clean start-up oscillator utilizing two crosscoupled voltage controlled current source-capacitor pairs as well as a source or great amusement at an Analog Devices presentation. But I suspect you are asking something else.

    no that was what I was asking, I think this will be a future project, it seems simple enough it's just hard to wrap my head around this schematic.

    btw what do the infinity signs mean?

    I was thinking maybe I could make an Oscar type circuit with an inductor picking up the earths magnetic field as the starting voltage/noise?

    I think the infinity sign indicates that the enabling voltage is capactively obtained (no resistive elements).

    I guess this could be noise driven. But it defeats the reason to use this oscillator in the first place.
