Abstract
An oscillator device based on a ring oscillator, in which temperature-dependent fluctuations in the frequency of the clock signal of a ring oscillator can be compensated by adapting the supply voltage of the ring oscillator. For this purpose, the supply voltage of the ring oscillator is adapted as a function of an ambient temperature, using a voltage supply circuit.
