Is it possible for any circuit to independently make its own trigger, sweep or oscillation without the aid of an AC sine wave?

Even a Schmidt trigger, attributed to being able to create the start of an oscillating circuit, has to get its start from an AC sine wave. It seems that no amount of tubes or transistors can ...
