Classification: CPC H | IPC H

Claim 0:
1. An oscillator, having an input terminal, and an output terminal providing an oscillating output signal of a predetermined frequency comprising:
a ring oscillator stage, having a first supply voltage response characteristic, configured to provide a predetermined first propagation delay depending on a supply voltage;
an RC oscillator stage, having a second supply voltage response characteristic that is inversely correlated to said first supply voltage response characteristic, operatively coupled with said ring oscillator stage and configured to provide a predetermined second propagation delay depending on said supply voltage, and
wherein said predetermined first propagation delay of said ring oscillator stage and said predetermined second propagation delay of said RC oscillator stage are each approximately one half of a period of said oscillating output signal of a predetermined frequency, so as to generate said oscillating output signal of a predetermined frequency and stabilise said frequency of said oscillating output signal to variations of a predetermined voltage range of said supply voltage.
