Abstract
A device generates a random bit sequence with a digital ring oscillator circuit comprising logic components. The circuit has an input node and an output node, wherein the digital ring oscillator circuit is designed such that oscillation occurs during a change of state of a logic start signal coupled on the input node, said oscillation having a fixed point, and wherein on the output node a random signal can be tapped having an arbitrary level curve.
