Abstract
A stabilized oscillator which comprises a ring oscillator with an odd number of inverters. The output of an inverter is driving a capacitor and the input of the a next inverter. A feedback element is configured for generating a first and a second current with a fixed current ratio between both, and for applying the same voltage over the ring oscillator as over a resistor which is connected in parallel with a current compensator. The first current goes through the parallel connection, the second current goes through the ring oscillator. The current compensator is configured such that the ratio of the current through the current compensator and a parasitic current component of the second current is substantially equal to the ratio of the first and second current.
