Abstract:	A relaxation oscillator exploits a noise filtering technique implemented with a switched-capacitor circuit to minimize phase noise. A 65nm CMOS design produces a sawtooth waveform, has a frequency tuning range of 1 to 12MHz and a constant frequency-tuning gain. By minimizing and balancing noise contributions from charge and discharge mechanisms, a FOM of -162dB is achieved, which is a 7dB improvement over state-of-the-art.
