Embodiments of the present disclosure may provide a relaxation oscillator with improved performance against phase noise error. The phase noise error may be reduced from sources whose power is greater at lower frequencies. To reduce the noise error, the relaxation oscillator may include chopping in the charging current driver; chopping in the trigger level generator; and/or chopping in the currents that feed the cells. A chopped amplifier may be provided to perform chopping of the input signals. |
