This paper describes the first achievement of over 20,000 quality factors among on-chip relaxation oscillators. The proposed Power Averaging Feedback with a Chopped Amplifier enables such a high Q which is close to MEMS oscillators. 1/f noise free design and rail-to-rail oscillation result in low phase noise with small area and low power consumption. The proposed oscillator can be applied to low noise applications (e.g. digital audio players) implemented onto a System on a Chip.
